goto &func; replaces the current subroutine with the called one
in the same way exec replaces the current process. Another
solution is to actually alias the two functions:
#!/usr/bin/perl
use strict;
use warnings;
sub foo {
print join(", ", @_), "\n";
}
*bar = *foo;
foo(1, 2, 3);
bar(1, 2, 3);
You might also want to look on search.cpan.org for modules in the
Sub::* hierarchy. One of them may give you a better interface.
