Passing a method reference and then calling it

[Martin Hess]

How do you pass a method reference and call it on a particular object?
I know I can pass it as a string and call eval, but I'm trying to
avoid that performance hit.

You could use a proc/lambda, and pass it just like any other object:
foo = lambda do
puts "word."
end

def test(bar)
bar.call
end

test(foo)

obj = "something"
method = :reverse
obj.send method # faster than eval

That works, but what if I want to store the method reference for later
use?

That is exactly what I was look for! Thank you very much.
