      T1 - type of object the function needs to act on
      T2 - type of object being returned
      Parameters:
      target - the value to return from the function
      Returns:

      Deprecated, for removal: This API element is subject to removal in a future version.
      Returns the composition of two functions. For f: A->B and g: B->C, composition is defined as the function h such that h(a) == g(f(a)) for each a.
      Type Parameters:
      A - input to composed function
      B - output of inner function
      C - output of composed function
      Parameters:
      g - the second function to apply
      f - the first function to apply
