Mutating type aliases about mutmut

[boxed]

How many of these do you have in your code? If there are just a few of them then I don't think it's so unfriendly. One could imagine having some other way to ignore lines, like a separate whitelist file (maybe even regexes?) though.

I have a lot of them. Like ~30 just in a single project.

I like the whitelist idea. But I am not sure what implementation I can suggest. Regexes seem a good idea, but this way I have to keep a consistent naming of things that I like to disable.

And while it will work well for type aliases (one can use *Type as a naming pattern, or Any* in my case), it won't work for any other cases.

For the whitelist, I was thinking something that acts just like the pragma but is in a separate file. You'll have to still run the full mutation testing but then add all lines (mutants?) you want to whitelist to a .mutmut-whitelist-mutants file or something.

There is now a more powerful system to do whitelisting and other configuration.
