Subject: boolean indexing for subset reassignment

Two years ago this answer was given:
http://mathematica.stackexchange.com/questions/2821/does-mathematica-have-advanced-indexing

Essentially, the answer was that Mathematica did not provide direct support for this feature (unlike say NumPy, R, etc.). Work arounds were suggested.

Has the situation changed?

Thanks,
