[plt-scheme] Is SchemeQL still being developed?

Hi everyone,

I was curious about the status of SchemeQL; has anyone thought of porting 
SchemeQL to work on top of sqlid?  Or has there been work on factoring out 
the SQL-constructing part of SchemeQL from being tied to SrPersist?

It's embarrasingly difficult for me to build SQL strings without the 
guaranteed well-formedness of s-expressions.  I started playing with 
sqlid-helper.plt, which is supposed to offer a similar domain-specific 
language for SQL queries, but I've run into a few limitations with that 
package which have soured me a bit.

I guess I'm just curious in general what the status of SchemeQL is, if 
people are using it.  Thanks!
