You can’ t because only methods can end with ?
i think he is asking, why not? of course, we know it is not currently
possible, but variable names with “?” may enhance readability.
consider,
x? = method_that_determines_some_status
…
if x?
…
end
by just looking at the name, we are pretty sure that x? is a boolean
(just like is_xx? methods return bools).
wc is better than,
if x
…
end
whether x is a variable or method…
it’s just an added character where one may happily use or not. But maybe
i am missing something deeper…
