in reply to Understanding Split and Join

What happens if the delimiter is indicated to be a null string (a string of zero characters)?

perl behaves inconsistently with regard to the "empty" regex:

my $string = 'Monk'; exit unless $string =~ /(o)/; my @matches = $string =~ //; warn join('=', @matches), "\n"; exit unless $string =~ /(o)/; my @letters = split( //, $string ); warn join('-', @letters), "\n";

[Corion]: Oh yay. The (external, not guided by me) programmers have chosen Moose+DBIx::Class for some implementation, and now seem to do 1+n SELECT statements for each row, as is usual when using ORMs.
[Corion]: So maybe I should investigate how to plug in a cache in front of DBIx::Class so I can do a ->selectall_hashre f and then satisfy the "sub"-selects from that cached single SELECT statement ...
