When I wrote this, I was thinking about implementing some form of
static types, because so much of the literature on monads relies on a
static type system. But I suppose that all you really need is a
consistently enforced evaluation order. The static types are not
really _required_, they just h

Well, users of monadic programming languages would say that
continuations are monads in disguise :-) And yes, monads are "just"
statically typed continuations in a side-effect free environment, but
my point was that implementing them in Chicken would be non-trivial,
unless you had an elegant way

Yep. The overheads (mainly in terms of complexity!) of native threads

1) Port PLT Redex to Chicken, to support the design of term rewriting

the following cool projects to be ported from PLT to Chicken:

Currently we're using guile for our scheme modules because we can't
