+// check-pass
+// 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.
