Given the clarification that this is in a taint-safe environment, I would be hesitant to use this.

• It uses a hand-rolled URL parser
• Example uses object method calling, code uses non-object parameter parsing (you are not collecting $self in the function)
• &err call uses '&' to prefix the call. This should only be used in certain cases, and this is not one f them.
• Complex patterns to read. Not easily verifiable.

Just my $0.02. With inflation, it is not worth much.
