The experimental notice in the documentation is there because we have not
frozen the API yet. But I know for sure that this is the
implementation it will be
and the type of regular expressions it supports will be the same as it is today.
I see no problem with using the re module even in production code as
long as you are prepared
to change your code if we change the API.
I can also say for sure that you will not get any more functionality
in the old regexp module at least not
