[Openmcl-devel] YAWRQ (Yet Another Wheel Reinvention Query): MySQL interface

The problem I'm having with CLSQL seems to have nothing to do with the  
FFI.  The problem is that there seems to be a big disconnect between  
the docs and reality.  In particular, the docs say that you can call  
the CONNECT function with no arguments and expect it to fill in  
reasonable defaults.  But what happens to me is:

? (connect)
 > Error: The value NIL, derived from the initarg :HOSTNAME, can not  
be used to set the value of the slot COM.HACKINGHAT.CL-MYSQL- 
SYSTEM::HOSTNAME in #<COM.HACKINGHAT.CL-MYSQL-SYSTEM:CONNECTION-POOL  
#x3000414A614D>, because it is not of type BASE-STRING.
 > While executing: CCL::%SHARED-INITIALIZE, in process listener(1).
 > Type :POP to abort, :R for a list of available restarts.
 > Type :? for other options.
1 > ^D
? (connect :hostname "localhost")
 > Error: Incorrect keyword arguments in (:HOSTNAME "localhost") .

? (connect :host "localhost")
 > Error: The value NIL, derived from the initarg :USERNAME, can not  
be used to set the value of the slot COM.HACKINGHAT.CL-MYSQL- 
SYSTEM::USERNAME in #<COM.HACKINGHAT.CL-MYSQL-SYSTEM:CONNECTION-POOL  
#x3000414A375D>, because it is not of type BASE-STRING.

And so on (and on and on and on).

I've sent a message to Steve Knight asking about this as well but he  
hasn't responded yet.
