Yes. Combined with setlocal/endlocal it can be a very useful feature.

And it's not so different from the *nix shell mechanism of somekey=somevalue command.

    On all Unix shells I know, the caller has influence on whether somekey would end up in his/her environment, not (like in Windows Batch) the callee. For instance, if I call from bash a script like this: 

    source gurgle.bash

    [download]
    no child is born and the environment changes will be reflected in my environment. If I call it like this: 
    gurgle.bash

    [download]
    or 
    bash gurgle.bash

    [download]
    I do get a child and my environment stays unpolluted.
