Otherwise we might as well > use parens to mean something else :) (assuming you refer to the use of \) Well, that depends. If you consider Arc 'if and 'with as well as CL (and many other Lisp's) keywords as corner-cases, then yes they're "corner-case escape hatch". Note that because sweet-expressions disables indentation processing inside parentheses, we try as much as possible to provide escapes such as these, so that we don't force the user into using parentheses (and thus force them to forgo indentation). > This sentence wasn't clear: > > "Currently, if a line begins with "group", the "group" is silently > removed.

Yes, SRFI-49 http://srfi.schemers.org/srfi-49/srfi-49.html defines group, and dwheeler based the sugar layer on SRFI-49 reference implementation. Currently we are investigating/debating to remove group and replace it with a one-character symbol.

Yes, comma means unquote. In addition, comma-whitespace is used in indentation processing to mean that the inner expression of the unquote is also processed using indentation processing. So: ` foo bar . nitz quux . , meow . . . cat fish ==> `(foo bar nitz quux ,(meow (cat fish))) ------------------------------------------------------------------------------ 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.
