Answer 1

Scala doesn't yet have much more than Java in terms of metadata like this. Keep an eye on the Scala Reflection project, but I doubt that will offer access to local variables anytime soon. In the meantime, consider a bytecode inspector library like ASM. Another big caveat: local variable names are lost during compilation, so you'd need to compile in "debug" mode to preserve them.
