I'm not sure I understand.
If I say this:
@foo[execname] = sum(bar);
Doesn't 'bar' have some type, at least by default? I had thought that
dtrace tracked types dynamically. It seems to do so when I cast a
value and assign it to "self->blah". It also seems to keep track of
types if I try to pass in something that can't work.
Why doesn't the expression have a type?
