Good question. I=E2=80=99m familiar with CM-Lisp (a common lisp variant) =
and *Lisp (which had a bunch of unusual characters, jealous of APL I =
guess) but I have no direct evidence of a scheme. Certainly none =
provided by Thinking Machines, but there is some peripheral evidence =
that it may have existed though it=E2=80=99s mostly circumstantial =
(e.g., Steele was there for a while, and Scheme did have support for =
concurrency).
