Re: Perl 5's greatest limitation is...?

[TilRMan]

That

#!/usr/bin/perl -w
use strict;

this();

is a runtime error, not a compile-time error (Update: nor a compile-time warning).

[Joost]

And that's a problem that's impossible to solve in any perl program that uses eval STRING, AUTOLOAD, objects, require, do, symbolic references, typeglobs and probably more constructs that make perl such a nice and flexible language.

If you're really worried about missing a subroutine, you are going to need some good tests, because there are loads of problems just like it that can't ever be detected at compile-time.
