The reflection mechanism for properties, constants and parameters is not
described in RFC but I do believe it should for constants part. Correct me
if I'm wrong there.

The reflection for ReflectionProperty::getDefaultValue the same for
ReflectionParameter is similar and I get that it possibly should evaluate
the value on each call. But what about constants which by their nature
don't change?
Does that mean that each time ReflectionClass::getConstant is called the
value is already evaluated and the return value always refer to the same
object instance. Is that right? I guess it is.

IMO it deserves to be described in the RFC.

In general I love the proposal was especially thinking of it for static
variables.

Cheers,
