I can not read the code beyond that line. I will be stuck looking at
that and thinking for a while.

If you replace the 3 with math.huge it keeps going forever, and because
1+1 = 2 (and 2+1=3 etc), we can combine a for loop, the input (i) and
math.huge to increase x until we exit the loop.
So:
for x=i,math.huge do
if x > i then
return x
end
end
Can also be written as:
local x = i
while x <= math.huge do
if x > i then
return x
end
x = x + 1
end
Adding with for loops is better because it supports floats. For positive b:
local c
for x=a,math.huge,b do
if c then return x end
c = true
end
And for negative b:
local c
for x=a,-math.huge,b do
if c then return x end
c = true
end
If b is 0 (or -0) the loop doesn't run, so we need special handling for
that, which's basically a "return a" right after the loop:
local c
for x=a,(b >= 0 and math.huge or -math.huge),b do
if c then return x end
c = true
end
return a
And so on...

I've been working on some stupid/troll code (mostly to bypass some

And ofc, because this is a stupid thing, it should be as stupid as
possible, so here's a bug: https://github.com/SoniEx2/Stuff/issues/1
Feel free to send pull requests! (or hate me :c)
(This is more of an experiment than an actual thing, so let's see how
it goes!)
What's the use case of this ?
