if a function such es .queryAll("...") returns a NodeList. However if I know that this list is actually an ElementList and I pass the .queryAll("...") result to a function that expects an ElementList in it's signature I am getting i warning.

'NoteList' is not assignable to 'ElementList'.

It would be great if a "cast" like expression could be used to suppress such warnings

[Editor note: the cast operator "as" was recently introduced to the language]

What are you asking for? NodeList and ElementList are not in any subtype relation. The cast won't change that, it just makes it easy to check what type it is. You could already overcome this by assignment or by using dynamic().
