in reply to return of hash-assigment in list context (bug?)

What version of perl are you using? With my
This is perl 5, version 14, subversion 2 (v5.14.2) built for i686-linu +x-gnu-thread-multi-64int
I get the results that I would expect, with no duplicated values:
$ perl %h1=(a=>1,b=>2); %h2=(a=>11,c=>3); print (%h3=(%h1,%h2),"\n"); print %h3, "\n"; a11b2c3 c3a11b2

    This is perl, v5.10.0 built for i486-linux-gnu-thread-multi

    Thanks a lot... so it's an already fixed bug and I can stop chasing my faults! :)

    Cheers Rolf

      It appears to have been fixed between 5.12 and 5.14, though nothing is noted in perl5140delta.

      perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

        I browsed thru various perldelta513* w/o spotting it.

        For those interested here a one-liner for testing your perl-version:

        lanx@nc10-ubuntu:~$ perl -e '@k=( %h=(a=>42,b=>2,a=>1) ); print "$] Bu +g: @k\n" unless @k ~~ [%h]' 5.010000 Bug: b 2 b 2

        I'll gonna update a non-smartmatch solution here...


        w/o smart-match for even older perl versions (maybe the bug was introduced somewhere)

        lanx@nc10-ubuntu:~$ perl -e '%h2=@k=( %h=(a=>42,b=>2,a=>1) ); delete @ +h{keys %h2}; print "$] Bug: @k\n" if %h' 5.010000 Bug: b 2 b 2

        Cheers Rolf

        UPDATE: replace version-vars s'$^V'$]'g in code-sections
