Changing permissions on temporary directories during testing

Let's say that I'm writing a test suite for a Perl module which creates files and then, optionally, moves those files to predetermined directories. To test this module's functionality, I would have to see what happens when the user running the tests does not have write permissions on the desti

In an effort to keep the source tree nice and tidy, I'd like to propose that we remove the following languages from the Parrot source tree: - languages/conversion/ This was added more than 3.5 years ago. It's supposed to be a BNF to Perl6 Rules translator. I don't think its ever been us
