Of course, it should be constant :) But I do not know if parse error
is constant evaluation error ;) I mean.. it is syntax error, widely-
considered instruction is not executed.

Nevermind :) I am too poor in english to provide my point of view

sth during compile-time", not "it is parsed at compile-time")

Include/require are both run-time.
