[erlang-questions] erlang / laziness
Sun Mar 2 12:32:05 CET 2014
I'm from a clojure background, where many things are lazy by
default, including fundamental constructs, like map.
(def x (map func lst))
;; func is not called on lst yet
This has been a source of annoying bugs.
In erlang, can I assume that _nothing_ is lazy?
[ func(X) || X <- Lst],
now, the "value" of the list-comprehension expression is not used
anywhere (and in a Lazy language like Clojure would not be evaluated
However, in Erlang, it's _always_ executed, as nothing is lazy by default.
Is this assumption correct?
