The problem with that is that people start learning that .foo means call
foo on the current object, and then they write:
method iterate () {
for (@.objs) {
.process($_); # oops
}
}
And they may even know the rule, but $_ is a hard thing to get used to
in Perl. I think it's best is "call a method on the current object"
looks the same everywhere it is used.
