Just the other night I came across the following. Consider 

use strict;
use warnings;

my %foo;
@foo{1..3} = ();
print keys %foo;
@foo{qw/1 2 3/} = ();
print keys %foo;

both ways to assign to a hash slice work fine and produce the same results as expected.

Now add the following line to it:die "strange .." if foo eq 'bar'; which should make perl barf a "use of bareword 'foo' " error - as we are under strict. But it doesn't!! At least for me. I tried this under Perl 5.6.0 (ActivePerl Build 623) on Windows and Perl 5.6.1 on Linux (2.2.14).

If you remove the first hash slice line (@foo{1..3} = ();) then it works (or better not works i.e. throws the bareword error) correctly.

Well, so my questions are:
