Hello,

by chance I have encountered an (inconsequential) mistake in the
"Tutorial for (co)datatype definitions"
(\src\Doc\Datatypes\Datatypes.thy). The function every_snd does not do
what it promises to do (both instances). There is no recursive call!

Dear Stepan,

Thanks for the report! It will be fixed in the next release.

If you find further errors in the (co)datatype tutorial, feel free to just drop me an email. I'm the main maintainer of that tutorial.

Best,
Jasmin
