Comment (by robe):

 For furthest one which we aren't going ot implement anyway -- that was a
 typo -- I meant ST_StartPoint.

 I think ST_StartPoint is slightly clearer because it more closely follows
 the convention of the other non-symmetric geometry function I can think of
 ST_Difference.

 E.g
 ST_Difference(A,B) -> returns a part of A

 Reading it out loud its not as clear as the others

 A contains B -
 A within B
 geomA closest point geomB -- hmm does sound a bit

 though
 geomA closest point to geomB -- if you add a to there its a bit clearer
