//! `unstringify!` (https://crates.io/crates/unstringify) is a proc-macro to
//! parse the provided string literals. It can partially simulate eager
//! expansion by recognizing certain macro names, such as `concat!` and
//! `stringify!`. In the default configuration, `macropol` uses `concat!`'s
//! fully-qualified path `::core::concat!`, which does not get recognized by
//! `unstringify!`. This test demonstrates the use of the `concat!` parameter to
//! address this issue.
