 By default, exporting closures that have variables bound through `use()` will throw an `ExportException`. This is intentional, because exported closures can be executed in another context, and as such must not rely on the context they've been originally defined in.

 PHP supports shorthand syntax for closures (since PHP 7.4), also known as arrow functions. `VarExporter` will export these as normal closures.
 
-Arrow functions can implicitly use variables from the context they've been defined in. If any context variable is used in the arrow function, `VarExporter` will throw an `ExportException` unless the `CLOSURE_SNAPSHOT_USES` option is used.
