Description:
------------
A Fatal Error "Undefined constant" is triggered when I use a namespace on an undefined constant, but not when I don't.

Test script:
---------------
<?php
try {
    echo \UNDEF_CONSTANT;
} catch (Error $e) {
    echo "Fatal Error NS : " . $e->getMessage();
}
try {
    echo UNDEF_CONSTANT;
} catch (Error $e) {
    echo "Fatal Error w/o NS : " . $e->getMessage();
}


Expected result:
----------------
One of these :
- UNDEF_CONSTANTUNDEF_CONSTANT
- Fatal Error NS : Undefined constant 'UNDEF_CONSTANT'Fatal Error w/o NS : Undefined constant 'UNDEF_CONSTANT'

Actual result:
--------------
Fatal Error NS : Undefined constant 'UNDEF_CONSTANT'UNDEF_CONSTANT

"Error Exception", not "Fatal Error". The Fatal Error happens when I don't catch the Exception, sorry for that.

Using an undefined not namespaced constant is accepted for
backward compatibility reasons, and it will be treated as string,
additionally raising a notice, see <https://3v4l.org/J0R4j>.

When namespaces were introduced, BC was no issue, so the more
correct behavior of raising an error (an Error exception as of PHP
7, respectively) was adopted.

So this is expected behavior, but it seems the documentation has
to be improved.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
