hey. how come this is exported? https://github.com/reagent-project/reagent/blob/master/src/reagent/core.cljs#L90

https://github.com/reagent-project/reagent/commit/ba995c2e0dc93e8cdad70107c2847294cce2c7fd

No idea really, the commit message mention LightTable so maybe that used Reagent somehow or something

It will affect optimized builds as the function and code it uses will be included in output?

yes, it prevents DCE which probably isn't too relevant

but it also creates the exported global for that which is kinda weird

@thheller Hm, yeah, DCE in this case would only same few bytes as most code is used by Reagent anyway. But I'll remove the export as there doesn't seem to be any reason for it to exist.
