I would rather have coroutines (a.k.a. stack groups) directly,
as several CL implementations have done.

I think call/cc is too general and powerful (kind of like goto,
only more so).  It's right for a language such as Scheme that
tried to have a small number of powerful constructs, but that
doesn't make it right for other languages.

BTW, T is excellent.
