in thread Search an array ref of array refs

What are you optimizing than? Execution speedup cq load time? Are you sure that it takes significantly more time to do an additional query to the server? I guess the connection is not closed between the statement. Maybe the DB is on the same box as the webserver.

And even if it takes some additional timeframe (probably very small, test it!) for the query, is it worth the worse maintainability of perl code vs the SQL code?

I generally would answer 'no', but your situation may be different. As ppl say: only optimize the code that needs optimization. Optimization leads to less quality code, so be sure you need it. Just consider what you are doing.

[Corion]: ... values to be used. For example, I think for headers, one would want to have various kinds of Content-Encoding headers, but for the get_parameters one would have various kinds of Bobby Tables
[choroba]: What about [metadoc:// Algorithm::Loops]?
[Corion]: choroba: Yeah, but handing off the request to Dancer,Plack, Mojolicious,LWP is easy once I have the data filled into some structure ;))
[choroba]: Algorithm::Loops
[Corion]: choroba: I'm using that to generate the permutations, but I don't know how the user can pass the intended values to my function in a sane way
[Corion]: I have a prototype that permutes the get_parameters, but the values used for the get parameters should be different from the values used for the headers and potentially for parts of the URL
[Corion]: But yes, in general, my approach will be "split the URL into another set of parameters, generate an array of allowed values for each parameter and then NestedLoops() over the set"
[choroba]: hmm... so you need something like bag from Test::Deep, but not for checking, but for generation
[Corion]: This has the dual use of easily requesting sequential URLs and also being suitable for testing
[Corion]: For testing, I want to skip all tests with the same value(s) once one test fails to cut down on the number of failing tests
