passing a function to lists:map
Mon Mar 22 12:49:51 CET 2010
ta(X) when is_list(X) -> list_to_atom(X);
ta(X) when is_tuple(X) -> tuple_to_list(X);
ta(X) when is_integer(X) -> X.
% this doesn't work
atomize(List) -> lists:map(ta, List).
% this does
atomize(List) -> lists:map(fun(X) -> ta(X) end, List).
What's the difference? Have I just got the syntax wrong, or is there
some fundamental reason I need the second version?
