Not really a poem, it just struck me how nice the second line of this code sounds:

for (@commands) { if (fork==0) { exec $_ } };
wait for @commands;

    wait for @commands;

    Hmm....

    • weight for commands (sell it to someone who needs a few pounds)
    • wait 4 @commands (i do batches quickly, like 1, 2, 3)
    • wait for at commands (xt commands are so 80's)
    • wait for @commands (please asks nicely)
