[erlang-questions] It appeared type error when I checked the code with dialyzer

[Solomon]

I define a function like this:

f(T) when is_tuple(T)->
  ...
  dict:to_list(T),
  ...
  Ret.

When I checked the code with dialyzer, it said, "The call
dict:to_list(T::tuple()) does not have an opaque term of type dict() as 1st
argument".

There were no function to determine whether a term was dict(). So how I
should fix this problem?

Thanks.
