But once you do that, any code you write can only be used by people who have 
your hack.

In Squeak the parameters are copies that just happen to be read-only, but is 
it this way in the other dialects?  I would expect the parameter to be 
read-only, but I would expect that because I would expect at the low level 
the "pointer" to the original location is being passed for efficiency (since 
an object copy could be expensive) and therefor must be read-only.
