Yes. I learned them both about two years ago having at that point become 
thoroughly peeved with "Java the language" and looking for other things. 
I've kind of settled with Clojure if people want me to produce Java 
applications purely out of personal choice as I know LISP and it felt 
familiar.

Only if you consider my complete ignorance of DSL-s and how to 'do 
them'. LMAO. This would be a personal  100% green-field venture, 
ground-breaking,  new territory,  pioneering never done it before kind 
of venture for me, to learn new tricks and things.

I hadn't considered generating byte-codes!
I've used Jasmin in the past and I actually own a copy of the JVM book 
from way back.
Now *that* would be interesting although Dalvik is slightly different in 
what it accepts as byte codes I hear.
  Strewth, the possibilities abound!
