I was showing Squeak off to a friend today, and while clicking around in a
browser to show off the system's organization, I ran across this method:

BlockStartLocator>>
pushClosureCopyNumCopiedValues: numCopied numArgs: numArgs blockSize:
blockSize
"Answer the size of the block"
^blockSize

There's no method tag / pragma here... so why does this method need three
parameters? I see six implementers of the message, though... are the extra
params there to deal with polymorphism without blowing up? If so, that's
kind of interesting, because I hadn't recognized that pattern before.

I was scratching my head and thought I'd share:)
