[Chicago-talk] canonical is_tainted()?

[Mike Fragassi]

Andy -- what was the is_tainted from your talk last night?
The is_tainted from the most recent perlsec isn't the same:

    sub is_tainted {
        return ! eval { eval("#" . substr(join("", @_), 0, 0)); 1 };
    }

but I recall that the one on your slide seemed to make more sense.
