I hardly see a reason to use CGI's HTML generation routines - the output is still hardcoded, so you don't really win a thing over just putting strings in your code. The only possible difference is it automatically produces well formed XHTML. Shrug. If I hardcode my HTML for a small script, I use a heredoc or something. Anything else, I use Template Toolkit II. (Literally everything; I'm starting to use it in command line scripts too.)

If you look around you'll see that there's hardly anything like a consensus that CGI.pm's HTML routines are The Right Way, and in fact some quite highly regarded folks will tell you to first look for another solution.

Just because a module offers some functionality, even if it's a core module, doesn't mean you have to or even should use it. FindBin f.ex is so badly broken I actually find it sort of embarrassing that it's in the core.

Makeshifts last the longest.
