Unless you ignore the A/W suffix. One could argue that this is more
intuitive as you could locate an entry in the list by searching for the
undecorated name and then look for the one with the appropriate suffix,
which is at most one line away. If you sort strictly alphabetically, A/W
variants may be a couple of lines away (e.g. FooA/FooExA/FooExW/FooW)
which could make finding the right variant slightly counterintuitive.
