Just out of curiousity, is it because standard Perl functions do not specify how many parameters they need at a minimum, so the compiler cannot tell if a function is satisfied? Because, if it is, couldn't we just use prototypes? For example: 
sub foo ($$;$) { ... }

my $curried_foo = foo( 1 );
my $return_value = foo( 1, 2 );

I'm thinking a source filter would be needed to convert 

sub foo ($$;$) { ... }

to

sub foo
{
    if (@_ < 2) {
      my $arg = shift;
      return sub { foo($arg, @_) };
    }

    ...
}

Wouldn't that work?

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
