// Issue #7526: lowercase static constants in patterns look like bindings
// This is similar to lint-lowercase-static-const-pattern.rs, except it
// shows the expected usual workaround (choosing a different name for
// the static definition) and also demonstrates that one can work
// around this problem locally by renaming the constant in the `use`
// form to an uppercase identifier that placates the lint.
