Real life seems to be relative, would it make any sense to apply
"policy" filters to something like the Rockyou list (one uppercase,
one digit and one special char as an example policy filter) and then
make a .chr file (name it policy-1U-1D-1S.chr)? I suppose a case can
be made that an all.chr is more versatile, but could you also say that
the filter is slower (I don't know if that is really true) and a
dedicated .chr file would be faster. Perhaps it's time I experiment
with exactly that :)
