Re^2: Detecting undefined subroutines at compile time

It seems like Perl can detect undefined subroutines at compile time..

Nope, that's still runtime.

use strict;
use warnings;

print "hello world\n";

foo();

Output

$perl func.pl
hello world
Undefined subroutine &main::foo called at func.pl line 6.

I'm not sure how big of a problem this really is. This is why you make test scripts and actually verify your code. But I also wish I knew a solution for this issue as well.

This is why you make test scripts and actually verify your code. I did make a test script and ran it to verify my code, as I clearly demonstrated. My problem was that my test was invalid due to my ignorance in the distinction between compile-time and runtime in this instance (also clearly demonstrated:). I'm here to learn, and I learn by making mistakes (sometimes in public).	[reply]
