Hey Ivan,
- You are missing such operators like || and && (former is string concatenation, latter is tests overlapping geometric objects).
You've probably noticed how easy it is to add operators to S-SQL. Patches defining additional operators that are commonly used are welcome -- || would be a good candidate.
- As PSQL allows defining own operators, I think it worth exporting s-sql::def-infix-ops or creating some more flexible user macro (one might prefer to use :concat instead of :||).
I very much agree. Wanna write a patch? ;)
Cheers, Marijn
