Description:
------------
This doesn't work.

for ($i = 0; $i < 2 ^ 10; $i++) {
    echo $i;
}

This does.

for ($i = 0; $i < (2 ^ 10); $i++) {
    echo $i;
}

Is it actually a bug or is that how op precedence is expected to work here?

Test script:
---------------
for ($i = 0; $i < 2 ^ 10; $i++) {
    echo $i;
}
