I would like to be able to do something like this:
const Something = 1;
const AnotherThing = 2;
$thing = 'Something';
$id = ThingIDs::$thing;
This doesn't work. Is there a straightforward way of doing something equivalent? Note that I'm stuck with the class; it's in a library I can't rewrite. I'm writing code that takes arguments on the command line, and I would really
like it to take symbolic names instead of id numbers.
