I would like to know what you would think of the following change in
We are really in the mood to make some change in the compiler to play
with the idea
for our research.
remove direct access to instance variables a la self
a class still defines instance variable but we cannot access directly
instance variables accessors are automatically optimized to use direct
access by the compiler.
simplicity/uniformity no distinction between state and methods.
no private iv anymore anymore (except if we try to have a clever schema
that lets the programmer writing self x while the byte code remove the
with this schema we could have private instance variables but be
forced to used a normal method to make public an accessor.
public accessor could be then
Applicability to Squeak:
- would break all the accessors that do something more that accessing
(self changed) but we could use a dedicated parser/compiler so that the
changes only impact a subset.
