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 are
ignored.
UNIVERSAL unfortunately imports import() from Exporter which means EVERYONE
has an import() routine. Thus, boom.
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...
}
