This might not be what you're looking for, but could help you do something similar - the benefit of this is that it's extremely quick and easy. While I like Perl's regex a lot, for this kind of thing I usually use a unix command like:

grep -r -l -I -s THINGTOSEARCHFOR DIRECTORYTOLOOKIN | cut -d: -f1

For which I have an alias in my .cshrc:

alias scour 'grep -r -l -I -s \!:1 \!:2 | cut -d: -f1'

The syntax is "scour thingtosearchfor directorytolookin".

To search every file in a directory (recursively) for a particular grep argument. Comes in handy sometimes. With the current options it just outputs the filenames, but you could easily tweak that.

[Corion]: On the upside, I spend a lot of time thinking this weekend about how to actually implement rate limiting for futures, and if things work out, maybe even loading a configuration from an external file makes sense
[Corion]: I've also found some interesting invariants that I have to think/write about more. A simple rate limiter will never change the order of the input, while a limiter that allows for parallel execution will change the order. But my API currently allows for bo
[Corion]: ... for both, and I'm not sure if I want to add the cruft from the parallel API (a token that you need to hold on to while you hold the lock) to the rate limiting API too, to allow seamless up/downgrades, or not.
[Corion]: Also, rate limiting will look great with await: my $token = await $limiter-> limit($hostname); instead of my $f = $limiter->limit( $hostname )->then(sub { my( $token)=@_; ... });
