LSL/Luau compile error "Out of registers when trying to allocate 1 registers: exceed limit 255" with over-initialized `for` loop

[Suzanna-Linn]

I don't think that this one is going to happen in real use, but just in case.

// VM Luau
default { state_entry() {
    float i;
    for (

The increment works well. Is it the RegScope line?
