There will be 42 Scheme->JS transpilers by the end of 2012.

Most of what you describe is a consequence of backwards compatibility
and maximum dynamicity. ClojureScript gets a pass on these problems
(for the most part) because of its focus for use and compilation
model. Agreed adding these capabilities into JS is a sticky situation
and not something that I envy. I'm glad smarter people than me are
working on it.
