Hey.. this isn't bad.. in writing even :)

Okay, I have a prototype of this written.. basically you can do the
following:

<!--#try-->
foo
bnar
<!--#var sgkjgdsjksdg-->

<!--#except-->

The exception was <!--#var err-->

<!--#/try-->

So, if an error occurs inside the first block, the second block is
rendered with err substituted for the variable (in this case it prints
exceptions.KeyError

This is pretty basic stuff, so I'm looking for ideas on where to take
this.

Anyone have more ideas?
