Kit is quite correct. I did glance at the code, but I must have been looking at the previous version. Sorry.

As -ssc type psmatch2.ado- will show, Leuven and Sianesi have already done #2! For a while the package was distributed with a C-language plugin, but the hassles of maintaining that (and providing it in several flavors) led to the routine being Mata-ized. Now whether it could be more efficiently Mata-ized I don't know; I imagine that if Bill Gould got his hands on the code it could be.
