Close, but it's a bit more like this:

$ cat my @files = qw/ a b c d e f g /; my $total_steps = int @files; my $step = 0; for my $file ( @files ){ $step ++; my $t = rand; $t *= 3 while $step / $total_steps - .01 > rand; print "$t\n"; sleep $t; print "\rStep $step / $total_steps\n"; select undef, undef, undef, 0.3; } print "Done\n"; $ perl 0.692567903622152 Step 1 / 7 1.5466213811873 Step 2 / 7 1.80846504071083 Step 3 / 7 0.564190293187867 Step 4 / 7 2.93620287911233 Step 5 / 7 0.822297130956301 Step 6 / 7 1.016940946008e+38 ^C

... according to my son who's trying to download a game from Steam.

[choroba]: The problem was bigger, as the test tried to call a method that didn't exist anymore
[marinersk]: :: ducking ::
[choroba]: because, someone renamed the method, but didn't notice it was used in the test, as the test was skipped
[marinersk]: Well, if the method doesn't exist, it would be hard to pass the test.
[choroba]: later, someone removed the new method, as all its usage places were safe, but didn't notice the test still used the old name
[choroba]: fortunately, it wasn't that hard to replace the method and fix a few remaining failures due to the changes we did to the codebase over the years
[marinersk]: choroba Sounds like a process improvement opportunity; tests may not all need to be run, but they should all be compiled with perl -c before check-in/promotion happens.
[choroba]: so, now I have the test, so I can start making changes in the code. Back to the original ticket, yay!
[marinersk]: I definitely love it when my $current_taask=& taskPop(); if ($current_task eq $original_task) { } is true.
[marinersk]: s/taask/task/g;
