This was *real fun* to track down. Here's a minimal test case of what
was happening:
#!/usr/bin/perl
use strict;
use warnings;
use HTML::TokeParser qwno_such_function;
print here;
I run that and it prints 'here', even though HTML::TokeParser does not
export 'no_such_function'. No

That produces:
:!perl -Ilib parse.pl
no_such_function is not exported by the HTML::TokeParser module
Its not UNIVERSAL::require, its UNIVERSAL (which UNIVERSAL::require must
unfortunately load).
use UNIVERSAL;
use HTML::TokeParser qw(wibble);
HTML::TokeParser defines nor inherits any import routine. When there's no
import, any arguments to use are ignored and any calls to Class-import
Michael G Schwern wrote in perl.qa :
There is a fix for this, something like changing UNIVERSAL::import to be...
sub import {
my($class) = shift;
return unless $class eq 'UNIVERSAL';
...do the export...
}
Oh yes, that used to be a major *kh* problem.
That's

Note that the following does not trigger this:

CGI has the nifty feature of auto-generating functions from its import
list to turn them into HTML generating functions:
