That's not correct.  Suds does match the method's returned type with that declared
in the 
WSDL.  There are two reasons for this.  First, it validates that what is returned matches

the schema.  Second, it uses this information to convert types between XML to the correct

python objects.  For example, xs:int converted to a python integer.

[1]. I agree.  A good enhancement would be for suds to display the return types as part of

the method signatures displayed when you print the client.

Yes.  See [1] above.
