Yes good point. foreach is a simple one. The others like foldl always
throw me. I am always going back to the man pages. K's foldl operator
is just a single forward slash ("/"). It is pronounced "over".
F / Vector is read as "F over Vector".
Example: Accumulate sum over a vector of integers:
+/1 2 3 4 5
lists:foldl (fun (X, A) -> X + A end, 0, [1, 2, 3, 4]).
Would be nice to just say this in Erlang:
0 + over [1, 2, 3, 4].
