Ignoring what existing DBD:: support, do you see anything in the fundamental 
DBI-defined API that is SQL specific and has no analogy for other DBMSs?

In my own effort to rewrite DBI itself (Muldis::Rosetta::Interface[|::*]) which 
wasn't constrained to just SQL-think, I thought through various matters and 
still ended up with fundamentally the same API that DBI has (Machine=driver, 
Process=connection,...) and in particular found that it could easily be agnostic 
to the DBMS query language and essentially just pass it through.  The largest 
design difference I have is that while DBI's interface wraps its driver 
counterparts, Muldis' interface is just a set of roles which its drivers 
("engines") compose and users invoke the driver/engine directly; hopefully DBIv2 
will do likewise rather than continuing the wrapper approach.

What hate mail, for what reason?
