Perl on Google App Engine
I recently started using Google App Engine and I have to say that I like it. The only thing I would change is support for other languages, namely Perl. I don't mind learning Python, but since I already know Perl it would be nice to be able to use it.
If anyone else is interested in using Perl on Google App Engine please Star issue #34 (do not reply to the issue with a "me too" or "+1", it just clutters everyone's inbox). You'll have to be logged into your Google account to do this.
There is also a Google Code project working on getting Perl ready for use in Google App Engine.
