Your edit to https://en.wikichip.org/wiki/mirc/optimization stating that "/set -l" is faster than "/var" is simply untrue. I have benchmarked both statements - 100,000 iterations of "/var %a 1000" takes 2313ms on my PC, and the same number of iterations of "/set -l %a 1000" takes 2344ms. I am going to revert that edit. If you want to have a copy of my benchmark script, happy to share it with you. Sophist (talk) 14:13, 11 September 2018 (EDT)

Apologies - benchmark command was incorrect - revised timings are 2750ms for 100,000 "var %a 1000" and 2610ms for "set -l %a 1000". So whilst it is 5% faster, "multiple /set -l to set local variables is NOT much faster than /var because /var has to parse the line and call /set for each variable anyway".
