Hello guys,

Just encountered this:
Erlang/OTP 18 [erts-7.0.3] [source-5991161] [64-bit] [smp:8:8]
[async-threads:10] [hipe] [kernel-poll:false]

Eshell V7.0.3  (abort with ^G)1> F = fun(_) -> true
end.#Fun<erl_eval.6.54118792>2> K = fun(Elem) -> Elem > 3
end.#Fun<erl_eval.6.54118792>3> lists:dropwhile(F, [1,2,3,4,5]).
[]4> lists:dropwhile(K, [1,2,3,4,5]).
[1,2,3,4,5]

Is this behavior expected?
Am I missing something?
​​


​Cheers,

Fxmy.​
