Hello, I am using
use function namespace\function_name; in my code and I get a ParseException.

TokenName: “T_function”
message: Imported namespace name could not be determined.

xdebug_message: TokenReflection\Exception\ParseException: Imported namespace name could not be determined. in /vendor/andrewsville/php-token-reflection/TokenReflection/ReflectionFileNamespace.php on line 227.

am I doing something wrong?

thanks
