    Eep, sorry.

    PPI is (originally) short for Parse::Perl::Isolated. It parses perl as a Document, without using perl itself.

    The "Signficicant Tokens" metric ignores lines, variable name lengths, string length, POD and just goes on the complexity of the code itself, and can be found using something like the following.

    use PPI; # Load a perl document my $Document = PPI::Document->load( '' ); my $significant = grep { ! $_->significant } $Document->tokens;

[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
