That's part of why you should write your logs in JSON format! But, yes, excellent point.

I wonder if overload.pm can cause "foo $bar" to return an overload'ed object since it should compile down to "foo " . $bar and you should be able to overload concatenation. If so, then it could return an object that stringifies to "foo XXXXX" somewhere inside of 'print'.

Sorry, I can't take the time to test that at the moment.

    Hm. You know, it can in fact do that (overloading both '""' and '.' does what one would want). The new object would need to store the left and right concatenated objects (potentially creating deep trees), but that can also solve the problem where a string is constructed then used twice. Nice!

    Good Day,

      I think just a flat list of values, at least one of which is a Text::Hidden object, would be sufficient. :)
