`declare function MV_OMIT_CFF<A..., R...>(cffFunction: (A...) -> R...): (A...) -> R...`

Similar to [MV_OMIT](/docs/macros/MV_OMIT), this will omit only the [CFF](/docs/options/flatten-control-flow) steps from the passed function. This can be useful to keep performance-critical sections unobfuscated but still have other AST passes applied to them.

## Valid Usage

```lua
MV_CFF(function()
    for i = 0, 10 do
        print('this is flattened!', i)
    end
    MV_OMIT_CFF(function() print('this isnt') end)()
end)()
```
