I have be interested the using SwitchPoints for the invalidation phase of
my call sites. As you may
recall I collect sites into an array as they are created. When they reach
some quantity I invalidate them
all and start over. It seems that using a switch point for this is
perfect except that I lose the ability
to walk the array. Perhaps I can use my new skills with FollowReferences
to find the sites give the SwitchPoint.
Its not clear to me how this applies to my stepping requirement. As each
point can only change once it seems
less useful in controlling the execution mode. I am using an intial GWT to
decide on a site by site basis if a suspend
is required. If I use a switch point then it seems like I have to replace
the point each time its used. Is this
what you were thinking?
thanks

By the way it starting to feel like a real Smalltalk envrionment
