string_set is currently only used in string_substr, but, when people are ok with this, can be used everywhere in core.ops, where a string register is globbered.

The behaviour of the following program has changed, is this correct?

  set S0, "test"
  set S1, S0
  set S2, "another"
  substr S0, S2, 1, 3
  print S1
  print "\n"
  end

Yes you are right.

Before:
test
now:
not

The questions are (and this is IMHO the same problem with PMCs):
- set vs assign
- what should this program do

Substr should generate a new string and stick that into S0.

If we want to build a fast version that reuses a string register, I'm fine with that--it's definitely useful in a large number of circumstances, large enough to warrant expressing both sets of semantics.
