in reply to Have I misunderstood the point of modules or just CPAN?

"Are all these modules written in other languages because they really cannot be done in perl alone?"

The good thing about Perl is TIMTOWTDI, and the same goes for CPAN. If you want a pure perl way to handle CSV files, go for Text::CSV_PP, if you don't care about it being pure perl and you'd fancy speed (like me), you'd go for Text::CSV_XS.

I don't see the problem here. Perl isn't great at everything. I'm not writing up a Perl program when find + xargs can do it better/easier. I'm not building something myself something when bzgrep will be faster/easier. (Although I do use ack more often than grep nowadays).

Perl isn't always the right choice. Often, yes, but sometimes other languages come in handy too. In the above CSV example, the XS part will most likely speed it up. I'm really curious how you'd think something like Net::SSLeay or ImageMagick would be created without compiling evil non-Perl code, though. And what modules using non-Perl code modules trouble you this much if I may ask?

[choroba]: Morning!
[Corion]: Hi choroba, Discipulus!
[Corion]: Yesterday I've been mulling over how to best generate HTTP requests from permutations of values but I haven't found a nice API for passing in the "template" of the HTTP request yet. I guess I'll have to do a SoPW for that
[Corion]: The API itself will basically be my $iter = generate_http_requ ests(method => 'GET', url => '/settings/:name', headers => ???, get_params => ['foo','bar']), but I'm not sure how to parametrize values in the headers and how to specify lists of ...
[choroba]: On the other hand, lots of options to receive the requests :-)
[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
