There remains #2, which converts keyword-argument pairs to a-lists.This requires only that it be lexically apparent what is and what is not a keyword, not that the actual set of keywords for a function be known.(Still awaiting a use case for (foo bar baz zam) where baz evaluates to a keyword at runtime.) I will also formally add #3 now, in which the keywords are syntactic sugar for procedure *names* like foo:bar:baz:zam:.
Can you explain precisely which problem you are trying to solve? It is still unclear to me wether you are trying to:
1) find an alternative mechanism that avoids the need for keyword objects (i.e. you view foo: as a symbol and want to keep it that way)
2) find an alternative mechanism that avoids the proposed parameter list syntax (with #!key, etc)
3) find an alternative implementation of the SRFI (i.e. you are OK with the specification)
