Absolutely.  Oops!  Here it is, belatedly, and possibly

The current package does much ‘worse’ comparatively:

However, you make an excellent point, and this packages's intended 
usage means that it will clobber the caller's environment, not 
just its own.

If I were to use this package (and I might—it's neat) I would 
almost certainly end up using it in a setting where changing PATH 
at all would cause unexpected and frustrating ‘bugs’.

Hmm…

Kind regards,
