The Ruby Programming Language [mirror]

Since a few commits ago, we no longer call `Gem::Specification.reset`
after each invocation of `Gem::Installer#install`. This means we don't
call it when the default Bundler is installed during `gem update
--system`. This causes no issues until the end of the upgrade process
when:
* The previous default Bundler spec is removed from disk.
* All specification stubs are turned into real specifications by loading
them from disk. But the one for Bundler no longer exists so
materializes to `nil` and regenerating binstubs crashes like this:
```
Bundler 2.4.0.dev installed
RubyGems 3.4.0.dev installed
Regenerating binstubs
ERROR: While executing gem ... (NoMethodError)

```
We fix it by more carefully managing the removal of the previous default
Bundler gem.

What is Ruby?
Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.
Features of Ruby
- Simple Syntax
- Normal Object-oriented Features (e.g. class, method calls)
- Advanced Object-oriented Features (e.g. mix-in, singleton-method)
- Operator Overloading
- Exception Handling
- Iterators and Closures
- Garbage Collection
- Dynamic Loading of Object Files (on some architectures)
- Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://github.com/ruby/ruby/blob/master/doc/maintainers.rdoc#label-Platform+Maintainers
