5.9.5 breaks funky $#

Maybe it should break it, cos it's some funky and quite
possibly just
plain broken syntax, but ...

$ perl-5.8.8/bin/perl -e '$foo=[qw(a b c)];print $#{$foo}."n"'
2
$ perl-5.9.5/bin/perl5.9.5 -e '$foo=[qw(a b c)];print
$#{$foo}."n"'
-1

With strictness turned on ...

$ perl-5.9.5/bin/perl5.9.5 -Mstrict -e '
    my $foo=[qw(a b c)];print $#{$foo}."n"'
Can't use string ("3") as an ARRAY ref ...

whereas perl 5.8.8's strict.pm is silent on the matter.

I'm wondering if #25808 is the cause? Maybe Andreas can run
his magic 
diff machine on either side of this patch?

Indeed, I think this is the cause.

JFTR, $foo is being evaluated in scalar context, returns
the number of 
elements in $foo (3), and "3" cannot be used as an
array reference. The 
call back in May was that this was the more desirable
behaviour.
