James Robertson offers this gem:
Three types for the Lispy-things up there so high. Seven for the Fortran in their days bygone. Nine for the Algol ones, doomed to try. Just One Type for the Code Lord all alone, in the land of Smalltalk where the messages fly.
One Type to rule them all, One Type to find them, One Type to bring them all and so enlightened bind them.
Smalltalk just rules.
