Let's step back a moment... to the ORIGINAL PROBLEM that was looking for a
solution:
"
Rust's internal iterators implement the protocol encoded in Rust's for
statement, but it's not possible to give them all a common trait or
implement
generic methods or functions taking any internal iterator.
"
1. Is the above really A PROBLEM ?
2. If it is a PROBLEM, then what are the plausible solutions that solve it
and keep Graydon happy ?
a.) Does the solution keep dot-notation ?
b.) Does the solution support no-arg iteration ? or similar ?
c.) Does the solution avoid breaking tons of code ?
d.) Does the solution avoid adding a keyword ?
e.) Any other hard requirements ?
