[ruby-core:90653] [Ruby trunk Feature#15446] Add a method `String#matches` to the Ruby core

Issue #15446 has been updated by duerst (Martin Dürst).
This looks like a good idea. Actually, I might suggest that we even go further: We introduce a new method and depreciate (and ultimately remove) the functionality of producing an enumerator by gsub.
(I wouldn't mind keeping producing an enumerator with gsub, but only if that resulted in actual substitutions.)
----------------------------------------
Feature #15446: Add a method `String#matches` to the Ruby core
https://bugs.ruby-lang.org/issues/15446#change-75819
* Author: CaryInVictoria (Cary Swoveland)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
----------------------------------------
`String#matches` would be an alias of the form "gsub(pattern) → enumerator" of [String#gsub](http://ruby-doc.org/core-2.5.1/String.html#method-i-gsub).
I frequently use this form of `gsub` instead of `scan` when chaining to Enumerable methods. That's because `gsub` returns an enumerator whereas `scan` returns a temporary array. This use of `gsub` can also be useful when the pattern contains capture groups, which is sometimes a complication when using `scan` (such as when a capture group is needed for back-referencing).
Here is a simple example of its use.
str = "Tina was friends with Mary and Sue. Tina and Mary loved to party. Sue and Tina went bowling every Thursday."
str.gsub(/\b(?:Tina|Mary|Sue)\b/).each_with_object(Hash.new(0)) { |p,h| h[p] += 1 }
#=> {"Tina"=>3, "Mary"=>2, "Sue"=>2}
The problem with using `gsub` in this way is that it is confusing to readers who are expecting character substitutions to be performed. I also believe that the name of this method (the "sub" in `gsub`) has resulted in the form of the method that returns an enumerator to be under-appreciated and under-used.
Again, I am proposing that an alias be provided for the form of `gsub` that returns an enumerator. I suggest `String#matches`, but the choice of name is secondary.
