Re: [Teem-users] new unu command: "unu env"

hi,

Can anyone who uses the key/value pairs now describe a scenario in  
which things would be corrupted or confused by the automatic  
propagation of key/value pairs?

Specifically, does anyone have code that takes as meaningful the  
*absence* of a key/value pair?  In such a case, the automatic  
propagation of the key/value pairs could create a problem.
