Well, I'm happy with it like that...

Paludis currently requires a particular ordering:

  opcat/pkg-ver:slot::repo[bracketed][another][...]
  cat/pkg:slot::repo[bracketed][another][...]

Bracketed things can be any of:

  [use]
  [-use]
  [opver]
  [opver|opver|opver...]
  [opver&opver&opver...]

And reserved for future deviousness:

  [key=value]

opcat/pkg-ver used with [opver] things is currently accepted (but
probably shouldn't be). It behaves as if the external op-ver is added
to the brackets with whatever combining operator the brackets use, or &
if there's no combining operator.

This isn't allowed for EAPI=0, so if you want to experiment you'll have
to either do it in user config files (which can take anything that's
legal for anything, and various extra things that aren't) or set
EAPI=paludis-1.
