Close, but no cigar. The problem with FixUnderscores is that it requires 
the code to be loaded under the old rules first. If you can't load the 
old code FixUnderscores is completely pointless. That's why I'm saying 
something that illustrates rewriting DURING fileIn / package load is so 

Basically, what I'm asking for is this: What process does someone have 
to go through when they file out code from Squeak 2.0 and into Squeak 
4.1? If it just breaks, I'd not be happy. If it asks you for example 
"hey, this looks like old code using underscore assignments, would you 
like me to convert this to the current style?" I'd take it.

BTW, there are other approaches that would make me similarly happy, this 
is just an example. I'm looking for a consistent story where we can tell 
people "oh, you got code from Squeak 2.8, here is what you do: ...."
