Some of ets funs (for example: ets:i/1, ets:delete/1)  are throwing bad argument exception when atom() name is used instead of tid() even if their spec are using tab() which is atom() | tid().

---- sample log here ---

You forgot to pass the {{named_table}} option to {{ets:new/2}}, so you can't refer to it by name in ETS functions. The documentation ought to be a bit clearer on this point. :/

The following works fine:

{code:java}
tab = ets:new(tab,[public, named_table]), %% note that it returns the tid()!
ets:delete(tab).
{code}
