in reply to Specializing Functions with Currying

i do not know if this is useful for anything, but
sub curry2 { my ($fn, $argstack) = @_; defined $argstack or $argstack = []; return sub { my $arg = shift; if (defined $arg) { return curry2 ($fn, [@$argstack, $arg]); } else { $fn->(@$argstack); } }; }
transforms a function f into a function which can be positionally parametrised, though named would pose too no problems. sample usage:
my $myprint = sub { print @_; }; my $curry = curry2 ($myprint); $curry->("a")->("b")->("c")->();
