should have been more specific. 'no' was to the first question...does he
have to do anything special. do they exist? clearly. the only time he has to
mess with it though is if he wants to customize a class of his own so that
it is directly enumerable.

usually people customize a class to be enumerable is to get performance
benefits in storing a specific type rather than a variant, default
collection. that's what i meant. the second most common is functional
clarity for the caller.

as for the code below, MyParticularObject can 'hint' a function param type
anywhere...even a proc function. so, i'm not sure what you mean.
