Is it just me, or has anyone else experienced semiotic overload
following the recent discussion?  ;)

What do you think about double dispach?  That's one of the GOF
patterns, right... i can't remember anymore.  I think it is still
relevant in Self, since Self doesn't have multi-methods.

Plus, i noticed that traits bigInt>>+ uses it.  :)

Do you have access to a Macintosh?  

As far as all this patterns stuff goes, i've always thought Charlie
Parker's comment on music theory is equally applicable to design
patterns: "Learn that stuff, then forget it and just play [hack]".
