Please take the opportunity to sort this list, too. Thanks.

Argh... Does that mean that your environment suddenly changes while
running? That you start running from the default environment (which
cannot be changed) and then switch to a the real, changable
environment?
This is going to cause a hell of confusion to users who for example
want to define a different console baud rate or such...
