I saw this comment. I thought I could help out here.

Did you check that after_each is actually called? Here it kept littering temp config files. If so: what was my mistake?

That's a bug on stainless' side 😃 When there's no statement with a semi-colon on the it context, stainless actually puts after_each right before it.

One way to workaround it is to add semi-colons at the end of the brackets, like here for instance.
