Maybe too dynamic :) Not many people would expect \p{IsBogus} is
completely ignored where.
'str' =~ / \p{IsBogus}/;
But in cases like
$str = $ARGV[0];
$str =~ / \p{IsBogus}/;
the code may or may not raise an exception and that's somewhat tricky.

Thanks. Sounds reasonable to me, too.
I would not call this a bug (not sure if you were suggesting that it
is) - if you need to check whether a property is bogus, your example
has_unicode_property is fine. But it would not be unreasonable for
utf8.pm (or something) to provide a function that delivers the same
information.
I agree.
