I don't see how returning NULL helps here. You can just as easily have
defined
the constant to be NULL. There is no value we can return that is not
definable,
and throwing an exception isn't an option.
You have 2 ways to check it further if you do get false back.
defined('class::constant') will tell you if it is defined and
ReflectionClass
::getConstants() will give you an array of all the defined constants
along with
their values. It is trivial to wrap this and throw your own exception
if the
constant isn't defined.

Description:
------------
to make it short:
if you try to get the value of a constant via
ReflectionClass::getConstant(...) and the constant name you specified
does not exist, the function returns bool(false).
but maybe you have really defined a constant as bool(false). then you
are not able to distinguish between these two possibilities.
in that case the preferred behavior should be to throw and exception or
return the null value.
