Research direction
Reproduce the provided p:nth-child() {} input in the Popcode editor and inspect the current error output. Trace the CSS parsing or validation entry point responsible for nth-child, then make the empty-argument case produce a useful error message. Done means the example no longer shows the unhelpful error and the relevant behavior is covered by an existing or added test.
