Hello!

This SRFI is a nice idea -- but would it be possible to not use
identifiers starting with ":"?
Bigloo, Sagittarius and STklos will by default treat such identifiers as
keywords, not symbols.

Bigloo:
1:=> (symbol? ':a)
#f
1:=> (keyword? ':a)
#t

Sagittarius:
sash> (symbol? ':a)
#f
sash> (keyword? ':a)
#t

And STklos:
stklos> (symbol? ':a)
#f
stklos> (keyword? ':a)
#t
