// Issue #7526: lowercase static constants in patterns look like bindings
|
|
|
|
// This is similar to compile-fail/match-static-const-lc, 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.
