Hmm.. I'd definitely prefer not to have this be forgotten if we add a second
double underscore literal suffix, but presumably there is something we could do
to make it not active code. Perhaps we could replace it with a
`assert(!DoubleUnderscore && "Doubleunderscore should be handled like above if
we ever get a suffix that could hit this")`
WDYT? I don't have the ability to do so, but just a suggestion and a 'patches
welcome' to whoever wants to do the work (@js234 @mikerice1969 @Sirraide ).
