today's hack: finding dependencies

$ perl6 -e 'my %seen; multi find-deps($file) { find-deps($file, 0) }; multi\
  find-deps($file, $ind) { say " " x $ind, $file; return if %seen{$file}++;\
  for lines($file) -> $line { if $line ~~ /^ \s* use \s+ (\w+[\:\: \w+]*) \;/ {\
  my $dep-file = [~] "lib/", $0.split("::").join("/"), ".pm"; next unless\
  $dep-file ~~ :f; find-deps($dep-file, $ind+4) } } }; find-deps("lib/November.pm")'
