in reply to Smartmatch alternatives

Can['t] use the exists() function either, because it's use on arrays is deprecated as well.

It wouldn't help any way. exists on an array only tests if the array element at a given index exists (ie. has not been deleted), and has nothing to do with what it contains.

Is there a proper, future-proof alternative that does not require me to sprinkle foreach test loops all over the place?

Like this:

if( grep /^\Q$scalar$/, @array ) { ## it's in there }

Of course, that uses the implicit $_; so perhaps you'd prefer:

if( grep $_ eq $scalar, @array ) { ## it's in there }

[Corion]: ambrus: Yeah, I read that, but it's somewhat vague as in what I really have to implement, and where/how my "other" mainloop should/needs to call AnyEvent
[Corion]: (or maybe I just work better from existing code that I munge until it works and I understand it rather than a short abstract text like "implement everything that's needed" ;) )
[ambrus]: Corion: I think in this case you can get away with only a stub for idle, one that always dies when you create it, because AnyEvent::HTTP doesn't use it, not even indirectly through AnyEvent::Handle or AnyEvent::Socket or AnyEvent::DNS.
[Corion]: The "and I understand it" part is optional.
