cljs.main makes no distinction between dev and release builds. in my experience release builds just take too long so that you often end up needlessly queuing builds by making edits while its still compiling

I needed to turn off {:infer-externs :auto} so I wrote {:infer-externs false} worked as I wanted but then I searched on github what are the valid values for :infer-externs` on documentation only refers to :all` and :auto so I tried random values like :none , :hello , true all worked same as false so what is the correct value to turn off

@thheller I have used cljs.main + advanced build + watch several times to detect problems with advanced builds, it can be quite convenient in that situation

@m373h4n doesn't matter, just go with false.
