# E0072

Warning name: `unqualified_local_using`

Unqualified local `using` alias.

A private `using` declaration brings names into the local package without their
package qualifier. That makes later references harder to update mechanically.
Prefer qualified references such as `@pkg.name`, or make the alias public when
the package intentionally re-exports it.

## Erroneous example

```{literalinclude} /sources/error_codes/0072_error/top.mbt
:language: moonbit
```

## Suggestion

Use the qualified name directly.

```{literalinclude} /sources/error_codes/0072_fixed/top.mbt
:language: moonbit
```
