> Do we actually call SourceProvider::asID on a null pointer? Why?

Null SourceProvider means something like "I have an unnamed source provider".  There are a few places in the code where we explicitly check for null SourceProviders, but the asID() method is called without such checks, and generally works OK except when it returns zero and that zero ends up in some HashMap in the bindings.
