That'll learn me not to hack and post to the TML at the same time - at least for the next 20 minutes or so. Seems that writing an invariant checker pings some of the same neurons in my noggin as distinguishing between Da Famous Tom R and Tom B/kaladorn. Keep in mind that PA is in the _early_ IW period - the TC has just formed, those who were in primary school when Strider et al buggered off have yet to reach flag rank, there are no known Terran-Vilani hybrids, the AZS is still quite capable of administering a proper and thorough shoeing to the TCN, etc. Alex
