traditional for loop, which use indexes: pattern description

[Ruslan Shevchenko]

 Good day, community.

It's about proposal about adding for of loop with access for index value.

Patterns can be reviewed at

So, what statistics we need:
 1) How many for traditional loops we have at all.
 2) How many for loops have form:

 for(int i=0; i<x.length; ++i)
 or
 for(int i=0; i<x.size(); ++i)
 or
 i++ instead ++i
 or
 i=0 instead int i=0
in all combinations.
 All of those loops we
So, how many such loops we have ? -- near 1/3 of all traditional loops.

 3) for, where condition is like it.next()
 4) for and while, where condition like it.next and which call remove.

Sum of 2 and 4 will give us number of optimizations for index loop proposal

I guess this is cover, but correct me If I wrong.

Regards !
