Hello YC,

this is not really true: While Racket doesn't pass keyword arguments
the same way as positional arguments for reasons of efficiency, it is
still possible to programmatically create procedures that accept
arbitrary sets of keyword arguments and process them somehow. Check
out the documentation of make-keyword-procedure [1] in the Racket
reference if you want to look into this.

CHICKEN however does pass keyword arguments just like positional
arguments.

That's a good point to keep in mind.

Sure, I'll stay in touch and I'll put any prototype code I produce
into a publicly accessible version control repository :-)
