XSLT itself is a way too much locked down - even simple things like 
substrings manipulation and loops aren't so easy to perform. Well, maybe 
I am too stupid for XSLT but from my experience bringing tag syntax in 
programming language make the code poorly readable and bloated. I've 
used XSLT for just one of my projects.

Deeply nested braces of lisp remind me of current MediaWiki parser.

Lua was highly valued here at computer lab, also Ocaml (not sure of 
proper spelling).
