ETS tuple in body

Dear list,
Something I probably should know better of. In ETS, if one of your
MatchBody is a tuple, it needs to be wrapped as a tuple:
MatchBody = case is_tuple(Name) of
true -> {{{Name}, '$2', '$3', '$4'}};
_ -> {{Name, '$2', '$3', '$4'}}
end,
case ets:select(my_table, [{
{Name, '$2', '$3', '$4', '_', '_'},
[],
[MatchBody]
}])
I need to do this because to make it work for Name values of both test and
{test}.
Is there a better way?
Thank you,
r.
