Same here, only Java wasn't in the marketplace yet, and I didn't wait
to try it to conceive of that scenario.

It's a fundamental mistake to name anything in terms of implementation
type rather than domain type.  For example, a bunch of invoices stored
as a 'List<String>' named 'slInvoices' is obscure, uninformative and
trenchantly stupid since the 'sl' tells nothing about the role of the
variable in the algorithm.  A much better name is 'invoices', and it
can be a 'List<String>' or 'Set<Invoice>' as the implementation
demands.  (The latter most likely is better.)  The name reflects its
purpose, not its irrelevant implementation type.

One of the core principles of object-oriented programming is to *hide*
implementation.  Hungarian notation (as commonly practiced) is the
stupid antithesis of that.

This is a very, very old debate and the winner was decided a looong
time ago.
