What part of the string do you want to delete?
You might assign "" to a substr, or you might use s///, or perhaps chomp or chop, depending on how you specify the part to be deleted.

Expanding on japhy:

$x = 'Just another COBOL hacker,'; substr($x,13,5) = 'Perl';
Saying substr($x,13,5,'Perl') would work as well, but I find it less clear.

I'd use substr().

    [Corion]: choroba: Yes, but the longer I thought about efficient hashes mapping the event type back to their callbacks, and how to keep them in sync, the more I thought that all that optimization might just not be worth it, even if it's horribly inelegant
    [Lady_Aleena]: My biggest problem with hashes at the moment is one with 2,501 keys.
    [choroba]: how many event types are there?
    [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?
