BTW, another option to consider: explicitly avoid the case of macros. In wart I have no way to state quasiquote without parens. I figure the point of s-exps is to do macros, so it's not a big hardship if macros have parens. "Syntax most of the time, drop down to s-expressions when you need macros." I realize that there are lots of other reasons to use group/split/enlist/grit. But if people are ok with it, this makes our job a little bit less circumscribed. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
