Sadly not yet… we plan to have real support for this in Pharo4.
The AOP solutions (both AspectS and Phantom) do *not* support point cuts on
sub-method
concepts like “instance variable access”.
The stuff I did for my PhD supports this quite nicely… but that I have not yet
ported to Pharo.
(The idea is to do an “engineering grade” pass over this and put it in Pharo
not as a research
prototype but as a real, production ready concept).
I really need to push this… people need it.
There is a way to do all this on a lower level (e.g. AST transformation or IR
transformation)… I will write a mail how to
do that later the weekend.
