[Codenarc-developer] ExplicitHashMapInstantiation - copy of Map

[<chr...@wa...>]

Hamlet,

For ExplicitHashMapInstantiation, should there be a violation if you pass 
in a Map (or any variable) to the constructor of HashMap? I'm thinking 
not. Is there a better, idiomatic way to make a copy of a Map?
