Description

It looks like *cljs-data-readers* is not being bound to *data-readers* where it should be.

At a minimum, cljs.repl/load-stream does not. The practical effect of this instance is that e.g. (load-file "some/cljs/file.cljs") will fail if that file or any other contains a user-defined literal tag. Similar behaviour exists elsewhere, e.g. (load-namespace 'some.cljs.ns) will not load a namespace that contains user-defined tags (I think that one is due to *cljs-data-readers* not being bound in the analyzer).

This is related to CLJS-479 insofar as it's another symptom of ClojureScript loading code in subtly different ways in multiple places.

I'm happy to do either of:

submit issues+patches fixing issues as I encounter them, or
attempt a more significant refactoring that sets up (hopefully) one and only one place where ClojureScript reads code (i.e. uses LispReader) so that behaviour can be consistent

I'm somewhat hesitant re: (2) insofar as the specific requirements of the compiler and analyzer and REPL may be divergent in ways that I'm not yet aware of, but it seems like it's worth a shot.
