Kevin Newton d5232fd7ae Temporarily exclude some TestRubyOptions test for parse.y 
The description has been updated when running with Prism to have
+PRISM, which means that tests asserting against the description
when running with --parser=parse.y will be incorrect if the
subprocess ends up using Prism. We need to fix these tests, but
we are currently disabling them in order to get this over the line.

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://docs.ruby-lang.org/en/master/maintainers_md.html#label-Platform+Maintainers
