error[E0277]: repetition contains no interpolated value that is an iterator
 --> tests/ui/does-not-have-iter-separated.rs:4:5
  |
4 |     quote!(#(a b),*);
  |     ^^^^^^^^^^^^^^^^ none of the values interpolated inside this repetition are iterable
  |
help: the trait `CheckHasIterator<true>` is not implemented for `HasIterator<false>`
      but it is implemented for `HasIterator<true>`
 --> src/runtime.rs
  |
  | impl CheckHasIterator<true> for HasIterator<true> {}
  | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  = note: this error originates in the macro `$crate::quote_token_with_context` which comes from the expansion of the macro `quote` (in Nightly builds, run with -Z macro-backtrace for more info)
