There are some `Methods for the .NET infrastructure' that are in
sys.text.regex. They are 100% undocumented but are used by the compiled
assembly. It is critical that we implement these exactly the same as MS,
because that will allow pre-compiled regexes to interoperate between the
frameworks. It would be great to get some input as to how much they can
look to see what these methods do. I know there are some other APIs
where we will face similar problems (JScript comes to mind).
