Passing a method as a parameter

Question

Is there are way to pass a method as a parameter without using a Proc object or block? The answers I've seen to similar questions rely on creating a Proc object.

def call_a_method_via_a_parameter( &some_method )
  # ?? call some_method and pass it a parameter ??
end
def my_method( param )
  puts param
end

call_a_method_via_a_parameter( &:my_method )

Answer 1

def bob(jeff)
  puts "hi #{jeff}"
end

def mary(meth, params)
  meth.call(params)
end

mary(method(:bob), 'yo')
=> hi yo
