Do either of these interest anyone:

1. a "literate mode" that assumes all lines in a script are comments
unless the first column is a special character (Haskell uses '>').

2. the ability to specify a step value in ranges, e.g., (0,2..18) for
even numbers in the range.

The first I've wanted for a while; I really like the idea of being able
to give primacy to comments. It would go with a filename extender (.lrb
for literate ruby, following convention; .rb or anything else would be
treated like a normal script).

The second occurs to me after reading the thread on iterating on integer
ranges.
