sub mysub : lvalue {
get {
return 'result for get';
}
set {
my $set_value = shift;
# ...
}
}
mysub() = 'test'; # will invoke set block with argument 'test';
print mysub(); # will invoke get block without arguments. result will be returned to print;
sub readonly : lvalue {
get {
return 'readonly value';
}
}
print readonly(); # ok
readonly = 'test'; # fails
sub writeonly : lvalue {
set {
my $set_value = shift;
# ...
}
}
writeonly = 'test'; # ok
print writeonly(); # fails
There are 2 export functions: set and get. If you don't want to use export, you may use full names

lvalue::get {
return 'something';
}
lvalue::set {
my $set_value = shift;
}
}
