Implicit return for when-elseWhen-otherwise statements

Isn't this doable with MuxCase or Mux1H?

Huh, I did overlook MuxCase, that's a good practical solution. I'll definitely switch to using that, thanks!

I do think it still makes more sense from a Scala perspective to have this at least supported by whens. It's unexpected that you'd be able to write:

val result = if (cond) {
    val1 
} else {
    val 2
}

but not

val result = when (cond) {
    val1
} .otherwise {
    val2
}

Though, I don't know how much weight "making the Chisel API look like Scala" holds :)

I think what you really need here is the Decoder design pattern.

From my RTL experience, I prefer using when only in the control path.
