Acme::ButFirst - Do something, but first do something else.

	use Acme::ButFirst;

	# Print a greeting, but first find caffiene.

	{
		print "Good morning!\n";
	} but first {
		print "I need a coffee\n";
	}

	# Count from 1 to 10, but first print a statement
	# about our counting skills.

	foreach my $count (1..10) {
		print "$count\n";
	} but first {
		print "I can count to...";
	}

	# Print our lines, but first reverse them, but first convert
	# them into upper case.

	while (<>) {
		print;
	} butfirst {
		$_ = reverse $_;
	} butfirst {
		$_ = uc $_;
	}

Acme::ButFirst allows you to execute a block of code, but first do something else. Perfect for when you wish to add to the start of a long block of code, but don't have the energy to scroll upwards in your editor.

Acme::ButFirst recognises both butfirst and but first as keywords.

Usage of Acme::ButFirst is lexically scoped. ButFirstification can be explicitly disabled by using no Acme::ButFirst.

Acme::Dont::t, Acme::ComeFrom, Acme::Goto::Line

Any use of this module should be considered a bug.

Strings in the form of " { work } but first { coffee } " may sometimes be incorrectly munged.
