in thread Flipin good, or a total flop?

I'm pretty sure that works the same way
my $i = 13 if $expr;
does, and is not to be trusted to continue to do what you mean.

No, maybe I'm wrong. Hmm.

Update: as long as you don't modify $start or $end except in cases where they were already set, I think you can count on this continuing to work, even if the my $foo if bar thing is "fixed". But I'd expect that if a warning is added for the my $foo if bar thing, that you'd get the warning with your code also.

    bar() if my $foo;
    is different from
    my $foo if bar(); # don't do this!

    The first case is equivalent to

    if (my $foo) { # $foo is lexically scoped to this block bar(); }
    just like how
    for my $foo (@foo) { # $foo is lexically scoped to this block baz(); }

    So if ((my $start =~ /start/) .. (my $end =~ /end/)) is perfectly happy.
