[Changes for 0.09 - December 22, 2004]

• Installing this module no longer requires SWIG. Yay!
• Fixed a spurious warning from t/1-basic.t.

[Changes for 0.08 - June 15, 2004]

• Object and Environment now has ->val and ->sym to easily create MzScheme objects from Perl.
• Fixed building and eliminated segmentation faults on Mac OS X.

[Changes for 0.07 - June 15, 2004]

• MzPerl now correctly supports end-of-file as end of ";__PERL__;" regions.
• All MzScheme code are now evaluated in Language::MzScheme::Env::__eval; this made Spiffy-based modules (eg. IO::All) work better.
• Avoid importing invalid symbols, such as '(OVERLOAD', into MzScheme space.
• Adds nifty call/cc example to bin/mzperl's POD.
• Suppressed harmless warnings under -w.

[Changes for 0.06 - June 14, 2004]

• Beginning of at least some module documentations.
• Massive refactoring for Perl method wrappers, resulting in better
• error handling and more robust symbol importing.
• The script/mzperl program now supports inlined Perl code, via ;__PERL__; ... ;__END__; blocks.

[Changes for 0.05 - June 13, 2004]

• Much more efficient vector<=>arrayref type conversion.
• Context symbols added to function definition and runtime object invocation with sigils; the default context is to interpret it as scalar if only one value has been returned, and as a list otherwise.
• Objects and code references now preserve their identity when casted into scheme object and later dereferenced with ->as_perl_data.
• Environment is now created with Language::MzScheme->new, which adds perl-specific bindings (perl-use, perl-require, perl-do, perl-eval) on top of the basic env.
• New utility, script/mzperl, a perl-embedded mzscheme interpreter.
• Full round-trip for non-self-referential data structures now works; you can now pass unblessed references into scheme. (Blessed references already works as object closures.)
• Proper error handling; scheme-level errors are turned into "die" calls; calls within eval{} will return scheme_undefined, but $SIG{__DIE__} will catch the actual error.
• Object closure invocation now demands a method instead of silently dying.
• Extensive tests for context, object, data, perl-calls and error handling.

[Changes for 0.04 - June 11, 2004]

• Backported to SWIG 1.3.19 and earlier versions.
• Methods refactored into Language::MzScheme::Object and Language::MzScheme::Env classes.
• All scheme value types turned into properly overloaded Perl objects; type checking methods, eg. ->isa('CODE'), are also implemented.
• Deep copying into perl data structure supported as $obj->as_perl_data.
• Previously exported symbols now become class methods for Language::MzScheme, with the prefix 'mzscheme_', 'scheme_' and 'SCHEME_' removed.
• Transparent procedure calls across perl/scheme boundaries.
• Perl objects and classes may now be bound as scheme primitives.
• To invoke perl objects from scheme, do this: (object 'method arg1 arg2 ...)

[Changes for 0.03 - June 9, 2004]

• Build cleanly on SWIG 1.3.21, which we now require.
• It is now possible to insert Perl subroutines as MzScheme primitives. (See t/1-basic.t for how.)
• Perl-based primitives can both accept and return lists of any size.

[Changes for 0.02 - June 7, 2004]

• Worked around automatic "swig -shadow" on Mac OS X, by not rebuilding lib/Language/MzScheme_in.pm by default.
• All publicly supported functions from "schemex.h" are now wrapped.
• Fixed ithreads building problem by setting scheme_set_stack_base().

[Changes for 0.01 - June 7, 2004]

• Initial CPAN Release.
