Perl in the Google App Engine (update: false alarm)
Instead of waiting for http://code.google.com/p/perl-appengine/
just add
Google App Engine for Go http://news.ycombinator.com/item?id=2525221
with
Campher: Perl embedded in Go (github.com) http://news.ycombinator.com/item?id=2532809
Hate to disappoint, but Campher uses cgo + the unsafe package, which means it Campher won't run on App Engine, which doesn't allow "unsafe".
