Ruby 3 has recently been released. Could we get support for Ruby 3 for using in bundle development? I’m referring to the shebang (#!/usr/bin/env ruby20) that one can specify for the language implementation of a bundle command. This shebang is somehow recognized by TextMate and it will automatically download the specified Ruby version if it’s not already installed.

This is the ruby20 command:

All it does it link to the system supplied version of Ruby, only the ruby18 command installs a version of ruby. Don’t see any reason to add a ruby30 command until it is system supplied. Any benefits 3.0’s use in a bundle item would likely be outweighed by is low availability outside of running code directly which can be done with TM_RUBY. Of course for extreme cases nothing prevents a bundle item linking more directly with a home-brew/etc supplied version.
