No and yes, it wasn't really what I thought

  I thought it would give the value of
#[Attribute(Attribute::TARGET_CLASS|Attribute::IS_REPEATABLE)] (65)

but it only gives you

Attribute::TARGET_CLASS (1)
Attribute::TARGET_FUNCTION (2)
Attribute::TARGET_METHOD (4)

see:

You can see at the unitest:

just ignore this part.. typeof used in other languages when you want to 
know what type something is of and I was hasty in my reply and guessed 
without really reading.
