Luke Gorrie’s comment to ‘Erlang: parallel-map and parallel-foreach’ article

Parallel map brainfsck implementation in Erlang:

%% Map function F over list L in parallel.
parmap(F, L) ->
  Parent = self(),
  [ receive 
      {Pid, Result} -> Result end  || 
         Pid <- [ spawn( fun() -> Parent ! {self(), F(X)} end) || X <- L ]
  ].

The notation [ F(X) || X <- L] means “The list of F(X) such that X is taken from the list L” .
