Looks nice. I had long considered doing something Meta-ML-like for 
Erlang, but wanted to start with something simple that didn't need a 
modified parser (not even macros or transforms at the simplest level), 
and then work my way up. The advantage is that it works today, without 
forking OTP or pushing an EEP to add metasyntax to R18. :-)

Note for anyone trying Merl: it doesn't work with R16B03 due to the 
broken syntax tools in that release. Use R16B03-1 instead.
