Also there *will* be the if-then-expression, the question is only

I didn’t realize it was imminent.
What about this:
if (if x > 10 then 1 else -1) > 0 then
;
You can do confusing things like this too right? I don’t think we’re
going to avoid confusion with the intrinsic or this syntax.
Yes, that would become valid syntax. However, I doubt you're gonna see
such code anytime soon, outside of obfuscated code contests (or vibe
coded AI slop). Your nested if example is pointless, because it is
equivalent to the much simpler:
if x > 10 then
;
You're more likely to see things like:
a := if x > 10 then 1 else -1;
instead of
if x > 10 then
a := 1
else
a := -1;
At least that's what I see in Rust code, which has a similar "if" as an
expression, as well as a "if" as a statement. People who have the
tendency to like functional programming tend to prefer the first form.
Every feature can be abused to write ugly code, but this one is not so
bad, actually.
