    23  go work init optionally accepts paths to the workspace modules as
    24  arguments. If the argument is omitted, an empty workspace with no
    25  modules will be created.
    26  
    27  Each argument path is added to a use directive in the go.work file. The
    28  current go version will also be listed in the go.work file.
