(Sorry about the removal of all the good stuff)

What about the following bit of horrible code?

#!/usr/bin/perl -w

my $var1 ;
my $var2 ;
sub blimey() ;

$var1 = "0" ;
blimey() ;

sub blimey() {

If you remove the "sub blimey() ;" line the compiler complains:

main::blimey() called too early to check prototype at test.pl line 7.

What's the reason and what can you do about it, short of putting all
the subs at the front of the code which looks horrible and makes it
hard to read!
