[ruby-core:87129] [Ruby trunk Feature#14697] Introducing Range#% as an alias to Range#step

Issue #14697 has been updated by shevegen (Robert A. Heiler).


I personally am not hugely comfortable with endless Range, but I understand
the reasoning given by mame for it. There is nothing shorter than omission
of characters. :D

Since endless Range was accepted, I think using % on Range, as explained by
mrkn, makes sense too. I personally like step more because it tells me 
more (somewhat similar reason for as to why I prefer to not omit an end
range in the ruby code that I write), but I think since endless Range was
accepted, accepting the issue request here makes sense too. (I am not sure
if anyone understood what I was trying to say, but in short, +1 to the
issue request.)

Ruby allows for different paradigms and writing styles and people can 
always decide for their own how (and what) to write/code anyway.

Feature #14697: Introducing Range#% as an alias to Range#step

----------------------------------------
In #13904, `Enumerator::ArithmeticSequence` has been accepted for the representation of a range with step value.
And in #12912, a new syntax of endless range `(1..)` has been accepted.

Combining these new features, we can write an endless step range like `(1..).step(2)` in Ruby 2.6.
It can be used for array slicing like python's `1::2`.

If `Range#%` is introduced as an alias to `Range#step`, we can write a step range like `(1..)%2`.
This notation is already introduced numo-narray.
