list handling functions
Thu Sep 18 21:23:48 CEST 2003
Maybe tomorrow I will be ashamed to have asked a question whose answer is
obvious, but here it goes:
Are there any ways to simply express a 'map' (or similar) function that
iterates over several lists at once? I use something like
map2(Fun, A, B) ->
map2(Fun, A, B, ).
map2(Fun, , _, Res) ->
map2(Fun, _, , Res) ->
map2(Fun, Ta, Tb, [Fun(Ha, Hb)|Res]).
but this seems to be general enough to be found in a library. Or maybe list
comprehensions could be used in a clever way?
thanks in advance,
