Assuming I can navigate git (you all might need to be on belay), I'll commit a symbol property 
version of sign (it runs  the testsuite in about the same time as the hash table version). 

The testsuite calls sign about 1.5 million times--I didn't try to time sign. Since kill(all)
erases $timer data, it's not easy to time functions using the testsuite.
