Description:
------------
func_get_args, func_num_args, func_get_arg functions executed inside assert('') work on assert's arguments, and not on arguments of function assert is in.

Because assert transparently handles variables scope, one could expect that it works transparently on arguments as well.

With all PHP functions accepting variable number of arguments and only basic type hints, such assertions are quite important.

Reproduce code:
---------------

function test()
{
assert('func_num_args()==2');
}

test('one','two');


Expected result:
----------------
nothing

Actual result:
--------------
assertion fails
