```Also, rationals are still numbers. They're just not "Lua numbers"
(objects

lets me have numeric for with rationals. Except Lua. (Python doesn't
have
numeric for at all so it doesn't count.)
```
```C++ does not have numeric for, so it doesn't count either.

Francisco Olarte.

```
```for (int i = 0; i < 100; i++) { printf("%d\n", i); }

Looks like it does, it's just more flexible than Lua's.
```
```No 'for' is more flexible than Lua's.

for a,b,c,as_many_as_you_like in myiter(anything) do
end

```
```Sorry, C++'s numeric for is more flexible than Lua, because it gives you
more control over the iteration.

You can also use rational objects which overload < and ++ in C++ numeric
fors, while you can't in Lua even with __add and __lt.
```
```C/C++ does not have a numeric for, it only has a generic for.

for (statement_list_1;statement_list_2;statement_list_3) do statement;

No restriction anywhere, although if statement_list_2 is just an
assignment most compilers will recommend that you put it in
parentheses.

```
```

for (type i = min; i < max; i += step) {
}

Why can't I do

for i=min,max,step do
end

in Lua? They should be equivalent.
