Something like this? (pulled out of WASTE.h and massaged):

OSErr 
WENew(*destRect, *viewRect, flags, *we)
    const LongRect *destRect;
    const LongRect *viewRect;
    UInt32 flags;
    WEReference *we;

This is doable.

I figured I was in for some XS code from the outset without having looked 
at the API, and I KNEW there was a reason for keeping a copy of SWIG 
handy (which I didn't :-( ).  I'll have to grab another copy at some 
point.

My own first glance reveals the only items NOT already XS'd to be Drag 
Manager support 
<Drag.h>, and WASTE's own <LongCoords.h> (needed to support selections 
larger than 32K).

I'm beginning to doubt my sanity for taking this up!  I'm going over the 
documentation with a fine comb, and will probably also post questions to 
the WASTE mailing list.

Thanks for the advice, and also for the XS tutorial.  More questions to 
follow as they come up!
