Have you tried prototypes?
Briefly. I don't fully grok the try/catch example in perldoc perlsub, so I may be missing something, but my failed attempts look like:
which of course does not compile. (There's also the issue that in order to really do higher-order functions with prototypes, I'd need to somehow examine fn's prototype and preserve it in the returned sub.)#! /usr/bin/perl use strict; use warnings; sub curry(&@) { my ($fn, @args) = @_; return sub { $fn->(@args, @_); } } &curry(+, 2)->();
I'm thinking that a source filter might help, turning builtins used as values into anonymous subs, but I don't know very much about source filters — I'm not even sure that they do what I think they do.
