I've definitely witnessed a tendency (online and IRL) to say "Perl isn't a GUI language - why write a GUI in Perl?". I think it's ridiculous. What languages do people think the hundreds of thousands of GUI apps are written in? Languages largely inferior to Perl, that's what.

Where online?

I haven't witnessed that kind of childish ignorance often, but I'm sheltered I guess , I don't frequent many programming websites beside stackoverflow
