This expresses my opinion quite succinctly. Overloading the
environment space to also control variant links would be a Very Bad
Idea, simply because the risk of name collision is too high.
Allowing links to indicate that they *should* be keyed off the
environment space, OTOH, isn't such a sin. eg:
${sysctl:hw.arch} and ${env:USER}
but this creates a new union space with yet another different syntax.
${space=sysctl, mib=hw.arch} and ${space=env, var=USER}
perhaps?
