Hi, 
Guess I got the answer as "erlang:function_exported" would 
Returns false for any BIF (functions implemented in C rather than in Erlang).
So lists:member/2 would have been implemented in C.
Sorry for the noise.

Hi,
Why "erlang:function_exported(lists,member,2)" gives me false where as the function is exported?
15> erlang:function_exported(lists,member,2).false16> proplists:lookup(member, element(2,proplists:lookup(exports,lists:module_info()))).{member,2}
Tried with some other functions randomly but got true. I tried with R14B and R16B. Is there any hidden reason behind it?
Thanks,marutha
