Revised the synopsis in the original post (well... now it is entering into tutorial territory)

I don't see how a tied filehandle with a default unhidden policy is going to be a good idea at all. Consider:

open my $LOG, ">", "/var/log/my_app.log"; tie $LOG, "Text::Hidden::Handle", force => "hidden"; my $ccn = Text::Hidden->new( "1234567887654321", default => "unhidden" + ); print $LOG $ccn; # OK print $LOG "Got CCN: $ccn"; # Oops! - premature stringification

Sure, interpolating a default unhidden string is always going to be "dangerous", but the fragility near a filehandle that pretends to force the values to hidden seems too far over the top. Unless I misunderstood your suggestions.

I have however, added default unhidden and hide_from options as well as manual mask forcing. Additionally, I have added localized policy setting so that one need not globally choose default unhidden (see examples in OP). Do you think that the revised synopsis addresses your concerns / describes a potentially usable tool?

Good Day,
    Dean
