Question

In Ruby, how do you refer to a function without invoking it, because foo is the same as foo() so it is already invoked.

for example, puts.class is the same as puts().class

Answer 1

You use method, like so:

o = Object.new
def o.do_it
  puts "I did it!"
end

m = o.method(:do_it)
m.call    # prints out "I did it!"
