Sub::Prototype - Set a sub's prototype

version 0.03

use Sub::Prototype;
BEGIN {
    my $code = sub { ... };
    set_prototype($code, '&@');
    *main::my_func = $code;
}
my_func { ... } @list;

This module only has one function, which is also exported by default:

set_prototype(\&some_function, '$$');

Sets the prototype for "coderef" to $prototype.

Shawn M Moore for the idea and tests.
