Hi y'all,

I'm looking for ways to type-check and otherwise validate the data that
my functions get. I've already asked about potential type-checking
solutions on r/scheme subreddit
(https://www.reddit.com/r/scheme/comments/1cni979/conventional_way_to_typecheckvalidate_data/)
with no definite/portable answer. I also found SRFI-92, SRFI-187, but
both seem to be withdrawn with a bit of drama around them. Is there a
more recent shot at data validation I'm not aware of?

I'm almost ready to submit a new SRFI, because I have an extensive
collection of type-checking primitives by now. Would that be useful,
what y'all think?

Best of luck,
