/*
* call-seq:
* ENV.clone(freeze: nil) -> copy of ENV
* ENV.clone(freeze: nil) -> ENV
*
* Returns a clone of ENV, but warns because the ENV data is shared with the
* clone.
* Returns ENV itself, and warns because ENV is a wrapper for the
* process-wide environment variables and a clone is useless.
* If +freeze+ keyword is given and not +nil+ or +false+, raises ArgumentError.
* If +freeze+ keyword is given and +true+, raises TypeError, as ENV storage
* cannot be frozen.
