Working with SharePoint web services - GetList and GetListAndView

Working with SharePoint web services is a challenge. Especially as it is not as well documented as you could have expected. So I often end up spending lots of time with small details which is mainly due to bad design. Let me give an example. Consider the GetList web service outlined below:

The web service contain one parameter:
listName
Whenever I use this web-service I always forget the it doesn't mean the name of the list, but the title of the list. Such a minor detail leads to waste of time - lot of time. And I'm probably not alone out here.

If you use the listName rather than listTitle you get the brilliant error message:
Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).

Does anyone know how to retrieve information about a list from it's listName rather than listTitle? As end users can rename lists easily the URL for the list is probably better to use than the name.
