I've got quite a bunch, but most of them will be fixed by tomorrow's meeting. The really tough ones are:
1) SI-6132 Reflection docs. Do we have to have the docs ready before the RC?
2) SI-5940 Macro users are effectively required to have scala-reflect.jar on library classpath. This is macro-related, but I insist we fix it in 2.10.0, because this bug will create tool problems (and as recent discussion at scala-internals has shown, the solutions aren't easy and vary from tool to tool). I have a fix [1], but it can be improved. Related investigations can take up to one day.
3) SI-5498 Reflection: ModuleMirror.instance doesn't work for nested and inner modules. This one has a quick and dirty fix that's already working [2], and a potential for a principled solution that would clean up name mangling for nested classes within the compiler. The latter touches the areas I never delved into before and will probably take me quite a lot of time.
