Rename test_piracy to test_piracies?

[hyrodium]

As I mentioned in #88 (comment), I believe it would be more consistent to rename the test_picary function to test_piracies, similar to how we have test_ambiguities.

I have no opinion on this.

But since this would be a breaking change, now (before the upcoming 0.8.0 release) would be a good time to do such a change.

[hyrodium]

Should we deprecate with @deprecate test_piracy test_piracies and release v0.7.5?
Or, can I make a PR to rename the function without deprecation?

[lgoettgens]

You can add a PR without deprecation to be released as part of 0.8.0 (if @fingolfin doesn't object)

I personally think this is pointless busywork, but as long as someone else does it and it doesn't cause me any extra work, I won't object :-)
