Perhaps more importantly: are the differences between Scheme and CL so much
greater than the differences among various Lisps? The syntax split is bigger
than in C/C++ -- C is a subset of C++, whereas useful programs don't hop
between CL and Scheme without work. But I think that was true of older Lisps
Scheme did diverge from other Lisps in using lexical scoping, as did T. Then
it got picked by Common Lisp and all the dynamic scoped Lisps are dead except
for e-lisp and lush. (Well, and maybe others I haven't heard of.) (lush is
dynamic in interpreted mode, lexical in compiled mode, to fend off
nitpickers.) And the e-lisp people talk about moving to CL or Scheme. So
here Scheme diverged and got followed.
I think some people in the Scheme world questioned whether macros were
necessary, and macros seem an essential part of the full Lisp experience, but
they're part of the Scheme standard now, so.
