I think you have been staring at your monitor too long ;-).
I agree it does look a bit nicer. But relative to the rest of the  
term, its not a big gain.

I have been thinking of DSEL stuff as well lately.  I was looking at  
Joe's ML9 and trying to see whether using that or prettier term  
structure is the better choice for certain types of metadata.

Boston is a nice town and its going to get cold soon...go outside and  
stretch your eyes for a few minutes ;-)
BTW, I am enjoying erlyDB...great work!!!
