Are you looking for the #method method?
----------------------------------------
irb(main):001:0> def a
irb(main):002:1> puts "hello"
irb(main):003:1> end
=> nil
irb(main):004:0> def b(f)
irb(main):005:1> f.call
irb(main):006:1> end
=> nil
irb(main):007:0> m = method(:a)
=> #<Method: Object#a>
irb(main):008:0> b(m)
hello
=> nil
irb(main):009:0>
