IEnumerable in the small in defined as just an interface; for example (.Net sourcecode):
C#
internal interface IEnumerable {
  System.Collections.IEnumerator GetEnumerator();
}
Which does nothing but define the need for a method called GetEnumerator that returns a IEnumerator.
If that's what you mean by "My references are to IEnumerable"; then following "your rules"; you should avoid saying:


Count() is not a method of IEnumerable. A state machine can learn; you could probably get a good estimate the 2nd time around; all other things being equal.

If the IEnumerable returns an object, you could even have it return a status report every so often; you're not limited to returning a particular type.


..because "your rules" are stipulating that we ignored all the extension methods that are linked to IEnumerable and by distinction all the sub types of IEnumerable. Meaning you can't imply its a "state machine" because that would require you to first acknowledge the many extension methods for IEnumerable; because (if you missed it), the extension methods are the bridging code between IEnumerable as an interface to IEnumerable as a state machine i.e. part of what's commonly known as Linq.

What value is there in ignoring reality; Linq (for IEnumerable) exists as a large set of extension methods and sub types, etc.

Whilst its possible to create your own custom interfaces and types to tie in with Linq; that fact alone doesn't discount the large part of extension methods, ... that are considered .Net System.Linq and which is directly typed to the IEnumerable interface.
