Well, now it's been said... Scheme is my all-time favourite language. The regularity of Scheme's syntax, and the way scoping works in the language, are certainly influential on the way I'm going about designing this weird thing.
It is simpler in some ways, mostly because scheme has a "syntax tower" where even the most basic things can be understood in terms of other things. Let can be defined in terms of lambda. Let* in terms of let. Letrec* is also not that hard.
Once you know this and the difference between definition context and bodies (which is simple) there isn't much to add. The top-level works mostly like letrec*. Internal definitions work like letrec* Libraries work like letrec*
