I love the idea of simpler loops.

‘’’

for (int i = 0; i < 42) { … } // run [0, 42)

‘’’

In my opinion if the compiler knows what the limits are it should apply ++i or —i.

‘’’

for (int i : 0 … 42 ) { … } // run [0, 42)

‘’’

That version would be probably my preferred version since it could simply mean taking i from range literal from 0 up to but excluding 42.

The range literal could be reused elsewhere.

‘’’

for ( N ) { … } // run N amount of times

‘’’

Many times I’ve needed to have a simple way to run N amount of times without specifying the loop iterator.
