Would something like "checking_closure_args" be better? In my CL I split these
between those that are common to checking and minifying, and those that are
specific to one or the other.

[Dan Beam, 2016/08/02 19:36:33]

it makes sense to split this by "checking" or not in your CL because you
introduce the notion of "compressing".  this doesn't quite do that yet.

I have faith in your CL and your concept, but I'd like to let /your CL landing/
make this distinction in the rare case we end up going in a different direction,
this code can stay simpler.

notice that I haven't renamed "compile_js" to "typecheck_js" anywhere yet
either...
