in thread Slicing with Arrow-Operator possible in 5.12?

Thanks!

Unfortunately there seem to be a compability conflict with hashes. For isntance $hr->{qw/this that/} already means $$hr{join $;,qw/this that/} !

That's an old feature (perl4 ?) for multidimensional hashes $hash{"this","that"}!

(for more see documentation for $; in perlop)

    You're looking for @{$hr}{qw/this that/}

    My criteria for good software:
    1. Does it work?
    2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
