If you want to implement the method as a binary message (with special
characters), everything is fine
Brilliant, so I was on the right track - sort of! Now for the important
question. Where are the special characters defined? I looked in Smalltalk,
and found a SpecialObjectsArray (along with a warning saying "don't touch
this"!). I am not planning to touch it, but I am curious to understand how
the system works.
The argument to a binary message is not undeclared; the simple fact
that the message is binary *implies* there will be a parameter.
Am I making sense?
Totally, that clears it up for me.
