That is something I have been considering for a while now. In it's simplest form it's relatively easy to do, but there are some caveats to consider. For example: Jump labels need to be unique and currently that is checked before any ifs are converted, so it could happen that a jump-label is removed by dead-code elimination and still causes an error.

Also, most code is never really "dead" in yolol. Even when using an if with an always false condition, the code inside it could still be reached with a goto. But I guess if you put code into a usually unreachable position nobody should be surprised that jumping to it gives strange results.

Tl;Dr: Good idea. Planned to be added, but might need some time to get it right.

So, I guess thats a decent attempt. It does not allow conditional defines or includes, but i think thats fine. Everything else works exactly as expected.

define foo=1
if foo==1 then
    :o1=1
else if foo==2 then
    :o1=2
    :err++
else if foo==3 then
    :o1=3
    :err++
else
    :o1=4
    :err++
end

compiles to

:o1=1

(It's not yet published. If you want to test it out you would need to compile yodk yourself from the develop-branch)

Update: You do not longer have to build it youself to test unreleased features. There is now an automated uild of the develop-branch: https://github.com/dbaumgarten/yodk/releases/tag/latest
