[erlang-questions] How do funs work ?
Wed Mar 28 10:51:56 CEST 2012
I have a function which returns fun as below:
make_fun(_, , F) -> F;
make_fun(Operator, [Operand1, Operand2|Operands], F) ->
F2 = case Operator of
plus -> fun() -> Operand1 + Operand2 + F() end;
minus -> fun() -> Operand1 - Operand2 + F() end
make_fun(Operator, Operands, F2).
When I call it as:
F1 = make_fun(plus, lists:seq(1,10), fun() -> 0 end).
Is F1 same as F2 below ?
F2 = fun() -> 1 + 2 +
fun() -> 3 + 4 +
fun() -> 5 + 6 +
fun() -> 7 + 8 +
fun() -> 9 + 10 +
fun() -> 0 end()
Also, is there any difference between funs that are defined at runtime
and funs that are defined at compile time in terms of how they are
