`declare function MV_INDEX_TO_NUM(tbl: {}): {}`

will replace all instances of named indexes with a unique number constant.

## Valid Usage

```lua
local foo = MV_INDEX_TO_NUM({total = 0, b = 2})
for i = 1, 10 do
  foo.total = foo.total + i
end
return foo.total + foo.b
```

turns into:

```lua
-- note that the order of the indexes has been changed as well
local a={[24453]=2,[19314]=0}
for b=1,10 do
    a[19314]=a[19314]+b
end
return a[19314] + a[24453]
```
