I've been saying for some time now that .= should mean exactly what one would expect
it to mean, method call and assign the result, for code like
$str .= lc

They're not quite equivalent -- I think eval's still wrapping a try/catch
around the call.

Dunno what .= would mean now . is method call. I'm sure som

Speaking to the practical side, I have written code that has to
disentangle
itself from the failure of a complex startup sequence. I'd love to be
able
to build a dynamic exit sequence. (In fact, being able to do &block
.=
{ more_stuff(); }; is way up on my list...)

foo() returns a closure that contains code that returns from the foo()
subroutine (the line that says "return $self") When that closure is
then called ...
my $block = foo;
print "Main";
$block();
... foo() is no longer executing.
That is,
print "Block";

Which is actually very, very nice.
So the question is: What happens when indexof isn't on the call chain,
but that inner closure is?

Main
Block
End
is my guess.

So, I must ask, what does this do:
sub foo() {
return my $self = {
print "Block";
return $self;
}
}
my $block = foo;
print "Main";
$block();
print "End";
That is, the block returns from a function
