Cool use for a macro: meta for

Instead of...

for 1..10 -> $i {
    for 1..^$i -> $j {
        for 1..^$j -> $k {
            ...
        }
    }
}

How about this?

meta for 1..10 -> $i, 1..^$i -> $j, 1..^$j -> $k {
    ...
}

Or, if the number of for levels might vary,

constant $LEVELS = ...;
meta for 1..10, { 1..$^previous } xx $LEVELS {
    ...
}

I have no idea if the above can be made to work, but I'm eager to find out.
