It's not meant to be used without reading the doc at least once.
Once read, of course, the $which values follow a logical plan and so
are memorable.
I'm thinking of the person who reads the code that someone wrote which
uses the "magic argument". They have no clue what it means, until they
read the docs. Of course, the person who writes the code might be the
same person who reads it, just six months later ;)
Constants and magic values suck, names rule, d00d ;)
