Instead of using error-pattern
you can add below a line with
//~^ ERROR `main` function is not allowed to have lifetime parameters
instead.
Also, I'd prefer new tests to be ui
instead of just compile-fail
. That way we also test the visual output.

Intrigued as to what the output is when you have fn main<'a, T>() {}
.

It would say lifetime, because one of the parameters is a lifetime. Would you go "lifetime nor type" parameters in such a case?
