Because "ultimate.answer(42)" is considered as "invoke method `answer'
of the value `ultimate', with argument 42".  See?  This is something
different from "evaluate `ultimate.answer' then invoke its returned
function object, with argument 42".

In Ruby, we can call a method whose name is also a local variable.

  print = 36
  print print, "\n"
