Yes, that sort of was the objective.

Not really sure what you mean by that.
The "default" constructor is the one with the TMaskOpcodes
(/TWindowsQuirks) parameters.

To be even more backwards compatible, mocRange should be disabled as well.
I'm a bit reluctant to do so, as having ranges is quite an improvement
over the old implementation (which had only sets).
Possible problem is the '-' inside a range: this would be no problem
in old code, but can raise exceptions in the new code.
