Compiler: Error when assigning to compile time properties
Some property need to be known at compile time. We already had checks
that the binding is a compile time constant, but there was no check to
prevent, say

    self.row = 42;

which wouldn't work or could even cause panic or miscompilation of
generated code

Closes #4037
