Hi,

This doesn't cover communicating errors to templates
but this journal at
"http://bricas.vox.com/library/post/catalyst-exceptionclass.html"
gives an example for creating custom Exception objects
that Catalyst can use.  Might be something here to
give you ideas (I know it did for me) but probably
doesn't qualify as lightweight.
