in reply to Free MSVC tools + Activestate to compile CPAN Modules

As a small, Perl-only starter set for the Unix Utilities, I now avoid downloading and installing cygwin and use the Win32 Unix Utils as found on http://unxutils.sourceforge.net, as the three programs needed by Perl are only tar, gzip and wget for good measure. With these, the ugly errors of mismatched cygwin1.dlls are gone, and these three programs are easily put where the perl.exe binary resides too.

    Yes, good point about the cygwin dlls. Also, make sure that your windows Perl is in your path *before* cygwin, otherwise you might end up using cygwin's perl by default.

[choroba]: can't you create a meta-key corresponding to the disjunction of the events?
[robby_dobby]: Corion: Heh. This whole thing smells of Strategy Pattern or MVC pattern.
[Corion]: And performance linear to the number of registered one-shots doesn't feel that bad. Maybe I should collect statistics on how many callbacks are outstanding ;)
[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 ;)
