It's a design decision whether to treat built-in interfaces specially or 
not...I used iterator as a general case of a protocol because everyone 
is familiar with it.

I really like the idea of having test suites as the majority of the 
"body" of protocols. First, it fits well with the current trend towards 
test-driven design. Second, it helps to address the complaints of those 
who say that they need static type checking to find type errors. Test 
suites are much more powerful for verifying conformance to an 
"interface" than static type checks. Rather than being defensive about 
why Java has interfaces and we don't we should point out that our 
interfaces are potentially much more disciplined than theirs.

Prothon's marketing schtick should be that it is like Python but 
optimized for better scalability to big apps.
