On all subsequent calls on said object, the singleton method would shadow the instance method and would ...

Likewise in Ruby: def a(b,c) b+c end a(*[4,5]) What is this called, when one passes a single array to a function which otherwise requires multiple arguments? What is the name of the * operator? What other languages support th...
