Macro rustc_middle::ty::print::with_no_queries

pub macro with_no_queries($e:expr) {
    ...
}

Avoids running any queries during any prints that occur during the closure. This may alter the appearance of some types (e.g. forcing verbose printing for opaque types). This method is used during some queries (e.g. explicit_item_bounds for opaque types), to ensure that any debug printing that occurs during the query computation does not end up recursively calling the same query.
