Inverse and Items
inv_z_=: ^:_1 To avoid distractions with numeric right arguments of inverse functions. -- Raul Miller 2005-10-16 13:35:31
FWIW, I prefer the current position that definitions like this remain in e.g. stdlib.ijs (which defines inverse=: ^:_1). I feel that the J kernel should be minimalist, and extras that rely on English words like 'inverse' or on notation like 1_000_000_000_000x for 1000000000000x belongs in human-readable jscripts -- even if almost everyone starts by loading those jscripts.-- EwartShaw 2005-10-16 14:38:17
I'm happy with the definition in stdlib, though I think I'd prefer that the rather verbose inverse be accompanied by the shorter inv (much the way that nameclass is accompanied by nc). -- Raul Miller 2005-10-16 15:27:47

I also think that stdlib should contain a definition for items ("_1). -- Raul Miller 2005-10-16 15:27:47
