Question

The code below returns true if @var is non-nil.

class MyClass
    def a_simple_method
        not @var.nil?
    end
end

When I use the keyword return like this:

class MyClass
    def a_simple_method
        return not @var.nil?
    end
end

it returns a syntax error:

syntax error, unexpected tIVAR, expecting '('
        return not @var.nil?
                       ^

What did I understand wrong about return?

Answer 1

It tells you to use ()

class MyClass
    def a_simple_method
        return not(@var.nil?)
    end
end
