    I get too wordy sometimes, but that's what i intended if you look at the
example code.  A basic shallow copy would be default behavior with the
option for a deep copy.

    Do you mean outside of the standard library too?  Is there something
wrong with having them both in the library either as separate functions or
one function with a boolean?
