KERML — Exponentiation should be right-associative

If you look at the following sample:

1 a = 2 ^ 3 ^ 4;
2 a = (2 ^ 3) ^ 4;
3 a = 2 ^ (3 ^ 4);

Both lines 1 and 2 will generate the same model in SysML v2 pilot implementation.
This means that exponentiation operator seems to be left-associative, which is unusual, as exponentiation is supposed to be right-associative.
