I'm not sure if I'd like it better or not. If we did something like
this though, I think I'd want to spell it a little differently.
I'm thinking that there might be some sort os pseudo section, say
ENVIRONMENT, so you could do:

    ${ENVIRONMENT:HOME}

You could even specify an ENVIRONMENT section in a buildout file to
provide a default. But the main reason I'd prefer something like this
is to not introduce a new variable-substitution syntax.
