in reply to "use lib" and architecture-specific paths

According to lib:
For each directory in LIST (called $dir here) the lib module also checks to see if a directory called $dir/$archname/auto exists. If so the $dir/$archname directory is assumed to be a corresponding architecture specific directory and is added to @INC in front of $dir.
Does that not actually work under some circumstances? Does it require the auto subdir to exist? I confess to never having developed any arch-specific modules so I haven't tested it.

    Thanks, this was the nudge I needed. I looked at the code and saw that lib had a bug fix at some point in this section. The version 0.5564 doesn't do it properly for locally installed modules. It only works for the site_perl structure where the version number of perl is in the path. This was corrected in 0.5565.

[Corion]: Meh. SQL window functions would even make pagination easy/trivial (but not performant), as rank() over (partition by user order by timestamp) / 10 as page would give me a page number for each item, with 10 items per page.
[Corion]: Of course, the query performance for "all items on page 10" is likely worse than rank() between 100 and 109 , but if that means I can write 15 lines of SQL instead of needing to think about how to partition things and how to encode the page size...
[Corion]: ... that would be nice. But alas, I'm currently tied to SQLite as minimum implementation, and it doesn't implement window functions :-(
[Corion]: And I'm not aware of any other serverless SQL implementation that even reaches the capability of SQLite, not to mention surpasses it
