[ruby-core:43449] [ruby-trunk - Feature #5534] Redefine Range class and introduce RelativeNumeric and RelativeRange

ruby-core #43449
Issue #5534 has been updated by alexeymuranov (Alexey Muranov).
More of my crazy ideas. Wouldn't it be nice to be able to write:
a, b = 0.5, 10.5
(a..b).each(Integer) do { |n| puts n }
----------------------------------------
Feature #5534: Redefine Range class and introduce RelativeNumeric and RelativeRange
https://bugs.ruby-lang.org/issues/5534#change-24916
Author: alexeymuranov (Alexey Muranov)
Status: Open
Priority: Normal
Assignee:
Category: core
Target version:
I started by commenting on Feature #4541, but ended up with proposing a new feature myself.
I suggest to redefine the behavior of Range class so that all empty ranges be equal:
(2..1) == (1..-1) and (2..1) == (1...1) and (2..1) == ('z'..'a') # => true
In other fords, ranges `r1` and `r2` should be equal if and only if `r1.include?` and `r2.include?` give identical results for all inputs. (Why is it not `includes?` by the way?) Thus Range would simply be a way to store certain infinite sets.
This change will result in not being able to slice an array `a` from beginning and from the end simultaneously with `a[1..-2]`. To resolve this, i propose to introduce `RelativeNumeric` and `RelativeRange` classes.
Each `RelativeNumeric` would be a `Numeric` with an "anchor", which is an arbitrary symbol. For example:
3.from(:bottom) # would return a "relative" 3 with "anchor" :bottom
One can define shortcuts `#from_bottom` for `#from(:bottom)` and `#from_top` for `#from_top`.
A `RelativeRange` is a range with relative bounds. If bounds of a relative range r are relative to the same anchor and the range is seen to be empty, it should be equal to *the* empty relative range with this anchor. For example:
(3.from(:center)..2.from(:center)) == (0.from(:center)...0.from(:center)) # => true
Now, to do what is currently done by `a[1..-2]`, one can redefine `Array#slice` to use instead:
a[1.from_bottom..(-1).from_top]
What do you think?
