Nested/local labels

[SamWilsn]

Example

I think we could support something like:

root:
    push1 .nested
    jump
    .nested:
        jumpdest

other:
    .nested:
        push1 root.nested

This example would define the following labels:

• root at 0
• root.nested at 3
• other at 4
• other.nested at 4

Necessary Considerations

• Probably should pay special attention how how this interacts with user defined macros (#18)
• Deeply nested labels root.nested.super_nested
• Parent references (maybe ..nested or super.nested or something else entirely)
