I've noticed a problem: the number/false conversion doesn't accept 
the "0E0" string returned by DBI as "0 but true" value:

>auto_increment primary key, Text varchar(255)) type=innodb"))
>  (sth.execute sth)
*** ERROR IN (console)@21.1 -- Unknown error
(gperl#sv->number/false '#<SV* #2 0x8537B64>)
>  (sv->string #2)

I've put a patch to the current gperl and to the p-dbi sent in my 
previous mail at this address:
(I've also added a more verbose message to stderr for the above case. 
BTW: I should probably change all ".../false" type and 
conversion-function names to "maybe-...")

With this patch, after rebuilding gperl (bruse gperl) and dopping the 
Foo table (mysql> drop table Foo;) it now gives:

DBD::mysql::st execute failed: Table 'Foo' already exists.
