i strongly support naming conventions that help people know at a glance 
if a term is a property/role or a class/concept.
Thus I rarely support a "silent has" rule.

I have found over many years of teaching and consulting that it is too 
easy for people to misuse classes as properties as vice versa but when 
naming makes it clear which is which, they make way less errors and 
reuse is increased.

i agree with the lower case .
some conventions use lower case for properties and upper case for classes.
