Thanks for the reply, I'll consider your advice more!

re: English, fluent writer, my spoken English is sometimes halting (it's not like I can go back and edit my vocal utterances, unlike in "written" English on a computer). re: Scheme, I'm not so sure if a Schemer would say I "contributed" to the Scheme language with SRFI-110 - there's significant resistance against indent-based syntaxes - but I know a few implementations have picked up SRFI-105 (Guile at least, I think a few others).
