Right, lexical variables in eval was probably added much later than
setq/setf, and I've never really written so extensive forms at the
REPL that this issue ever came up. I'll fix it right away.

This is touching some of the hairier corners of the compiler, so don't
be too surprised to find compiler bugs when using labels etc. I'll
look into this too, shortly.

Thanks for the bug-reports.
