You can also delay the use with:

    Object::Trampoline::Use->connect( 'DBI', ... ) 

which delays everything until one of the DBI object's
methods is really called. Problem there is that if DBI
is going to fail for any reason you won't find it out
until fairly late in the code (vs. at the start with
use).
