This is not possible, due to how QML works. Your second line is a
binding, which you can only use if a property was already declared. This
information is static, and an error will be thrown if you use myprop on
the left-hand side of a binding if no such property exists.

If this is Creator 3.1, then please file a bug and attach an example
project and a description how to reproduce. I do not observe such
problems in my daily work.
