Thanks -- so what does sprintf('[U+%04X]' do, and why is it coming out as What[U+2019]s new?

    It replaces every character in that character class (basically: the unusual ASCII control characters, plus anything outside ASCII) with:

    1. opening square bracket, followed by
    2. capital letter "U", followed by
    3. plus sign, followed by
    4. the numeric value of character being replaced, in uppercase hexadecimal, padded to a minimum of four digits, followed by
    5. closing square bracket

    It's a regular expression I use quite... regularly. It makes any non-ASCII characters stick out like a sore thumb, so you can see exactly what characters are in your string.

    perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

[Corion]: Also I found that I can't conveniently weaken an array slot, which also is inconvenient, as I want my one-shots to disappear if the caller discards them
[Corion]: choroba: Currently two or three that my program handles (WWW::Mechanize:: Chrome), but there might be more that become interesting
[Corion]: But I don't expect more than 100 to be active at the same time, so I'm not really sure if there is a not-too-fancy data structure that is maintained with few lines of code where the performance is better than the linear scan ;)
[Corion]: But I should do a mock-up program so that others can see what I'm talking about ;)
[robby_dobby]: Corion: I hope you know all too well that passing around "fancy" datastructures is a recipe for disaster :-)
[robby_dobby]: As in, it's-too-fancy- that-it-will-be- messy-to-handle
[choroba]: bit vectors as keys?
[robby_dobby]: Hmm, I keep falling asleep at my desk, while maintaining an active appearance. Am I getting old?
[robby_dobby]: Every time I fall asleep, there's a small guy in the dreams, shouting "Whoo!" and it jolts me awake. :/
[Lady_Aleena]: robby_dobby, at least you aren't driving. I seem to always be driving somewhere in my dreams and end up at a weird house.
