(general reply): Oddly, I get completely different results from you all.

//var %n = 10000, %ticks = $ticks | WHILE %n { dec %n | if 1 == 1 . } | echo -a * 1 == 1 . results: $calc($ticks - %ticks) ms

//var %n = 10000, %ticks = $ticks | WHILE %n { dec %n | if (1 == 1) . } | echo -a * (1 == 1) . results: $calc($ticks - %ticks) ms

//var %n = 10000, %ticks = $ticks | WHILE %n { dec %n | if 1 == 1 { . } } | echo -a * 1 == 1 [[ . ]] results: $calc($ticks - %ticks) ms

//var %n = 10000, %ticks = $ticks | WHILE %n { dec %n | if (1 == 1) { . } } | echo -a * (1 == 1) [[ . ]] results: $calc($ticks - %ticks) ms
