I think Nim is pretty cool (conceptionally, haven't used it yet) and full
of wonderous features: From the hands down awesome, like the a la carte GC,
its AST - based macros and optimizations and effect system to positively
weird stuff like its partial case-insensitivity (foo-bar == fooBar ==
foo_bar == foobar == fOOBAr; wat?) or its method calls (obj.foo(bar) ==
foo(obj, bar); I don't even). Overall it's appealing to me and certainly
seems easier than rust. And, of course, I'm interested in new
implementations of clojure.

I'm optimistic about is the possibility to optimize the common case of
dynamic features by term-rewriting macros.

However, I have some concerns about it:
- How will nim's static types interact with dynamic features; can enough
types for the compiler be generated by inference?
- Could it be that nim is too rich a base as a host language? For the added
indirection and complexity: What do we gain over transpiling to C and
generating an accurate type map for BoehmGC?

Concerning porting Clojure: I think ClojureScript's experiment of putting
protocols/deftypes first in the bootstrapping chain has proven out, so I'd
start with figuring out how protocols are best represented (nim's
multimethods?). Since nim already has first-class functions, special care
has to be taken how they interact with the IFn protocol.

What do you think?
