[ruby-core:78793] [Ruby trunk Feature#13048] Better way to do Regexp.new(Regexp.escape("some string"))

Issue #13048 has been updated by Colin Fulton.


It would be nice to have a real/more-idiomatic way instead of a hack, and that hack doesn't support duck typing, while adding `#to_regexp` to `String` does.

----------------------------------------
It is relatively common to call `Regexp.new(Regexp.escape("some string"))` or `Regexp.new(Regexp.quote("some string"))` in Ruby (a quick search turns up over half a million matches in Github). However, these seems rather cumbersome. It would be nice to have a class instance method on `Regexp` and/or an instance method on `String` to go directly to an escaped regular expression.

Personally I'd rather see `#to_regexp` added to `String`. This would not overlap with the functionality that `Rexexp.new("string")` provides since that doesn't quote the `String`.

It would also be good to see [9846](https://bugs.ruby-lang.org/issues/9846) addressed along with this request so one could more easily duck type a method to accept both `Regexp` and `String` arguments.

Thoughts?
