k externs inference is really coming along

return type inference works

and if you have an existing externs and you make a typo - you will get warning

there’s obviously lots more validation we could do

like basic validation of Google Closure Library usage (or Google Closure compatible stuff) - but that’s for another day

I’m not planning on doing any further new work prior to the release - so now is the time to kick the tires with master

to suss out any issues

I’m am willing to look at smaller tickets w/ patches that people want to get into this release

There are no regressions when ClojureScript master is used downstream with Planck (Planck passes its tests)

@mfikes excellent
