__construct with call_user_func… can any1 help me out?

i wonder. can abstract classes have static methods?

the default behaviour with == (two equals) is to convert them both to a common type
if you use trebble compare (== and they are different types, the comparison will fail

so 1==1.0 is true, and 1===1.0 is false?

yes

or more precisely, can static methods of abstract classes (if at all possible) be called as abstractClass
