OK. Does a newbie need to use it? To empty a collection? (Or whatever?)

I'm trying to get at what should be a very simple thing without going to  
the metal, as it were.

One thing I wasn't clear on is whether Bert's suggestion:

aColl removeAllSuchThat: [:anElement| true].

Is okay, and why it's okay while many of the other similar approaches were  
not.
