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..

kind regards -botp
