New Comment:
I disagree, this function should fail even when used as first argument
(also according to docs).
If you allow it to be passed as first argument, but not as second or
third, etc., you create only chaos.
It's much more cleaner to let it fail everytime.

Right.
I think this shouldn't be fixed.

Note: Because this function depends on the current scope to determine
parameter details, it may only appear in the first argument to a
function. Thus
myfunc1 (myfunc2 (func_get_arg(1), 7)) OK
myfunc1 (myfunc2 (7, func_get_arg(0))) Error
myfunc1 (7+func_get_arg(0)+func_get_arg(1)) OK
myfunc2 (func_get_arg(0), func_get_arg(1)) Error
If you must pass this value of func_get_arg() not in the first
argument, assign the results to a variable, and pass the variable."

Dmitry, this script should fail for all of those:
<?php
function doTitle($a = NULL, $b = NULL) {
print "doTitle: $a, $b\n";
}
function doHead() {
doTitle(func_num_args());
doTitle(func_get_arg(0));
doTitle(func_get_args());
}
doHead("1", "2");

Manual says:
"Note: Because this function depends on the current scope to determine
parameter details, it cannot be used as a function parameter. If you
must pass this value, assign the results to a variable, and pass the
variable."

Well, that's true then. But I'm not sure how important this bug is :)
