This is Scheme, procedures don't have to have static type signature. I
may just allow all of the following three styles at the same time:

  (import (prefix dbi dbi:) uri-generic)

  (dbi:connect '(postgresql [host . "example.com"] [database . "blubb"]
                            [tty . "log"]))
  ;; OR
  (dbi:connect "postgresql://example.com/blubb?tty=log")
  ;; OR
  (dbi:connect (uri-reference "postgresql://example.com/blubb?tty=log"))

Ciao,
Thomas
