It does not currently work, because Acme::Bleach uses this technique:

    open 0, $0;
    eval some_func(<0>);

which opens the .exe instead of .pl.   If Damian had written it that way:

    seek DATA, 0, 0;
    eval some_func(<DATA>);

then it will work with PAR.  Suggestions on how to intercept or rewrite
the "open 0, $0" part is welcome, because it does seem very obvious to me.

At the very worst, I can ship a PAR::Filter::Bleach as an example of
input filtering, along with PAR::Filter::PodStrip.

Oh, and another question for list members.  If I say:

    pp -f Bleach foo.pl

should pp apply Bleach to foo.pl only, or to all modules it requires?
Should we ad another -F switch to mean "filter dependencies", so one
can say:

    pp -F PodStrip -F RemoveWhitespace -f Bleach -f ProductActivation foo.pl

Or are there other better syntax/semantics suggestions?

Thanks,
