Just at a quick glance, I think LFE is a Lisp-2? At least, it bears more resemblance to Common Lisp than Scheme. I don't see any 'funcall' function though, so I could be wrong.
To me this looks like a not as well developed version of LFE.
It depends on what you mean by not as well developed. If by that you mean maturity. Probably, its much newer and has just had its very first early alpha release.
Wasn't wondering about namespace count as much as maturity/completeness.
LFE is a Lisp 2. It has ':' which is the equivalent of funcall.
