Subject: [ruby-core:48362] [ruby-trunk - Feature #5781] Query attributes (attribute methods ending in `?` mark)


Issue #5781 has been updated by ko1 (Koichi Sasada).

Target version changed from 2.0.0 to next minor

I changed target to next minor because no discussion on it.

Feature #5781: Query attributes (attribute methods ending in `?` mark)

Pretty sure this has come up before, but I'd like to revisit b/c I don't understand why it isn't allowed.

Sometimes I define "query" attributes, and in those cases I'd like the reader method to end in a `?` mark. Currently I have to do:

    # @attribute
    def foo?
      @foo
    end

or, if I don't mind a shadowing bare method,

    attr :foo
    alias_method :foo?, :foo

So why not just allow:

    attr :foo?

Currently this causes an error. But why? It just seems like a waste of potentially cleaner code.
