[plt-scheme] poll: keyword syntax

Three reasons why I prefer to maintain the current state:
1: I am conservative (not in all respects but with respect to languages, natural or computer, I am)
2: The # is generally used for special things. A keyword is a special thing. #:k seems better visible than :k or k:
3: People (me included)  may be using identifiers starting and/or ending with a colon.

I think that #: belongs in the range of #', #&, #, , #,@, etc.
It is always possible to adapt your readertable such as to insert # before a colon automatically (as an option please, not as a 
fixed rule)
You might even consider an option to suppress showing # when preceeding a colon.

Keywords should be easily visible (with some emphasis) in the program text. #:key is much better distinctive than :key or key:.
I agree that we need some characters to have special effect (parentheses, brackets, quotes, double quotes, backslashes, vertical 
bars, braces, white space and #) I prefer the set of special effect characters to be as small as possible. mho,
