What is the use case of this feature?

In GNU assembler, 2 use cases:

1. using in macros to avoid name clashes;
2. writing quick one-off code (e.g. in a lecture) and not having to invent better, globally unique names.

In RARS, the first use case is covered by label renaming, the second remains relevant, and a third one is added:

3. writing code in the same style as in the GNU assembler.

Actually it's the third one that prompted me to port this feature (after my students tried to use local labels in RARS programs and failed).
