Name mangling has outstripped the abilities of lonesome '$'

[scabug]

I think if I set my mind to it I could construct a lot more examples than this, but any number of collisions are too many. Is there any other character which could be utilized during mangling? It looks like this situation may improve in the future, as somewhat discussed here:

Regardless, I think it would be worth figuring out something better which works on java 5. There's simply no way so many different things can be encoded with dollar signs and have it all come out clean in the wash.

class A_+
class A_ { class plus }

This will give you a probably random choice of A_+ and A#plus in your A_$plus.class file.

scala> val a = new A_
a: A_ = A_@33d88c1f

scala> new a.plus
java.lang.NoSuchMethodError: A_$plus.<init>(LA_;)V
	at .<init>(<console>:6)

See also #1994, where dragos says "This has to do with the mangling scheme for class protected members, which needs to be changed."

Please reassign, I am not going to work on this, even though I might have had something to say about it as some point. There's simply no way I can keep on fixing bugs that are unrelated to either the optimizer or specialization while writing my thesis.

I can totally respect that. Focus on your thesis. I wanted to get a handle on this one anyway.

This works for me in Scala 2.9.0.r24145-b20110130020134:

scala> class A_+
defined class A_$plus

scala> class A_ { class plus }
defined class A_

scala> val a = new A_
a: A_ = A_@35235feb

scala> new a.plus
res1: a.plus = A_$plus@66176ccc

This is not fixed. Please don't close my tickets.

I just took approx 1 min to fix the duplicated "$"'s in the title and the comments, because frankly I'm sick of the whining.

I didn't know SJWs could get sick of whining. That's promising!

You screwed up the "fix" so I'm closing.
