In fact, it is not a bug, it is a compiler feature :-)

The compiler assumes that the identifier MyClass is a class only if it finds:

  something AS MyClass

Or

  CLASS MyClass

Before the real use of the class.

So you must add CLASS Printer at the beginning of your code.

This behaviour may hopefully change in the future :-)
