no, i think you take this too far. it makes a lot of sense in a language
like ruby, but does require a seperation between assignment and
reassignment, if you will. in other words x = "a" would not necessarily 
be the same as x = String.new("a"), [of course a new literal could be
used] in the later case you are creating an object, x, and making it a
string. in the former you are reassigning the object, x.

unfortuanltly a couple of ruby objects are not passed by reference,
notably FIXNUM. personally, i have already run into a couple instances
where this "knocked me off my horse", and i think it a bad idea to mix
things up like this. perhaps there is good reason, but if it is one of
speed, i'd rather buy a faster processor and more memory that have this
inconsistancy.

yes, but not replacement of contents.

no, no copying.

(aside, would it be possible for ! methods to be an automatic creation?
just seems like there might be a way to define a method such that the !
version of it is automatically is deduced from it and that this could be
used through out ruby. just a thought.)

i think there are some deeper consideration to this. if ruby were to
take one more step in the direction of OO, becoming a Radical OOP, i
think it would discover another level (or at least semi-level) of power.

since everything is a subclass of object, there's no reason that objects
can't switch identities above that. we would be able to call-back on
such reassignments and create all sorts of neat "automagical" stuff.
also one could conrol class access at a much finer level.

it would not force us to use pass by assignment instead of pass by
reference. in fact the opposite is true.
