I need to have >posfixed keywords, <ident>: to be compatible with the Bigloo >compiler. RScheme and some other systems also use postfix keywords. I'd recommend that keywords be standardly postfix, or ambidextrous. Does anybody have much code that would break if symbols of the form foo: were considered keywords rather than variable names? I'd guess that most instances of symbols of that form are either uses in data, where it doesn't matter what the evaluation rule is, or uses for macros where keywordness is desired. I don't really know, though. Opinions?
