Depends what you mean by "this" and "fixable". Certainly it's impossible
for any variable that can be read at any point to always reflect the
existence of a variant that may not have been defined yet.

Issues of this type could be mitigated if we parsed portfiles in two
passes, but that would no doubt bring its own surprises.
