One-line method definitions

Ruby
1

I’m new to this forum, so I don’t know if it’s the right place to
discuss this. I still give it a try:

I’d love to see a non-verbose way of defining one-line methods in Ruby.
This would especially be useful for methods with constant return value,
for the sake of duck typing. For example,

def visible?
true
end

It would be much nicer if we could write these methods like

def visible?: true

What do you think?

There is a one line form for you already:

def visible?; true end

Whether you use it depends on the style you prefer. I avoid writing
methods in such form as the return value is kind of hidden.

The only case I consider using it is definition of an empty module or
class:

module Role; end

I agree with you that the return value isn’t apparent at first sight,
also the semicolon looks somehow alien here.

That’s why I’d like a shorthand notation that’s both, short and clear.

For modules/classes I prefer to write

Role = Module.new

This way I don’t need the semicolon and the end for the same reasons
mentioned above. But since methods aren’t objects in Ruby, this approach
doesn’t work here.
