As for 'step' word: It seems like for now IMO this is the best suggestion :
very explicit, anyone knows what "step" means especially in context of
loop, clear that "step" belongs to for-in construction(not to range itself).
for i in 0..<10 step 2 {
}
for i in 0..<10 step -2 {
}
for i in 0.1..<10.5 step 0.5 {
}
all are mapped to needed ranges/intervals under the hood
Do you want some custom Range-specific methods to provide steps for loop -
no problems, use what you need. But don't force any of us to use
(0..<10).striding(by:2) for myriads of simple loops in our code.
I want to see such constructions in our Swift. Who is with me ? :)
