Currently, a keyword like `type` fails compilation as (a path segment of) a field name, for no clear reason. Trying to use `r#type` instead leads to the `r#` being part of the field name, which is unhelpful¹. Don't require the field path to match a `macro_rules!` `expr`, use repeated `tt` instead. I can't tell why this was ever required: The internal stringify macro was introduced in 55091c9#diff-315c02cd05738da173861537577d159833f70f79cfda8cd7cf1a0d7a28ace31b with an `expr` matcher without any explanation, and no tests are failing from making it match upstream's `stringify!` input format. Special thanks to whoever implemented the unstable `macro-backtrace` feature in rustc, otherwise this would have been nigh impossible to track down! ¹ this can likely be fixed too by some sort of "unraw" macro that turns `r#foo` into `foo`, but that's a separate change not made in this PR

Motivation
Currently, a keyword like
typefails compilation as (a path segment of) a field name, for no clear reason. Trying to user#typeinstead leads to ther#being part of the field name, which is unhelpful¹.Solution
Don't require the field path to match a
macro_rules!expr, use repeatedttinstead. I can't tell why this was ever required: The internal stringify macro was introduced in 55091c9#diff-315c02cd05738da173861537577d159833f70f79cfda8cd7cf1a0d7a28ace31b with anexprmatcher without any explanation, and no tests are failing from making it match upstream'sstringify!input format.Special thanks to whoever implemented the unstable
macro-backtracefeature in rustc, otherwise this would have been nigh impossible to track down!¹ this can likely be fixed too by some sort of "unraw" macro that turns
r#foointofoo, but that's a separate change not made in this PR
