Help me answer this question for a colleague: Why is it that Perl can manage to tell you about this problem: 
use strict;
$foo = 1;

[download]
(that is, it will flag the variable as undeclared), but it has no qualms about letting this slide: 
use strict;
use Module qw(fubar);
my $a = foobar();

[download]
(that is, it won't catch the undeclared function call until run-time).

My cow-orker is in charge of the "build process" for our system, and his Makefile does a nice job of syntax-checking everything before assembling the "build file". However, undeclared (usually misspelled) subprogram names like the second example above drive him to distraction. "C wouldn't let you do that!", says he.
