I'm exporting a bunch of classes from a library using @JsExport and friends. For some reason, a private inner class in a completely separate module, that I haven't annotated to be exported in any form, is conflicting "Javascript name generated for this declaration clashes with another declaration". Any thoughts?

Recent versions of kotlin removed js namespacing so if you have a class with the same name in two different kotlin dependencies it might cause these clashes when both are transpiled to js
Don't quote me on this though 😀

Neither the outer class nor the inner class is a duplicate name. It's very strange.
Also, why would they remove the namespacing?

I guess I can see that. I'm figuring out that trying to make a Kotlin/JS library accessible from JS is a tricky proposition and a little wild west.
On a different note it would be nice if the compiler automatically renamed overloaded functions, perhaps based on the parameters.

^ the compiler does, that's the 
_a5d3z
postfix you can see on function names when you don't specify 
@JsName
it's not really readable of course

Does it? Because the compiler fails for me saying that javascript name clashes for overloaded functions.
For exported classes.
Also, getting errors around the fact that extensions inside a class clash when the method name is the same even if the classes that are being extended are different. Here is an example:
Copy code
@ExperimentalJsExport
@JsExport
class TheClass() {

  fun TextLine.before(charIndex: Int): TextLine {
    ...
  }

  fun Pair<String, TextAttributes>.before(index: Int): Pair<String, TextAttributes> {
    ...  
  }
}
This causes an error ... but why?
JavaScript name (before) generated for this declaration clashes with another declaration: fun TextLine.before(charIndex: Int): TextLine

Interesting, maybe name mangling is disabled when using 
@JsExport
? I'm pretty sure this compiles fine if you don't export it
That would make sense, mangling is very ugly when seen from JS
