I think you want --no-scope-shadowing on the sub functions. It is not
terribly well explained in the documentation; I struggled to get my head
around it a bit the first time.
With
```
function echosomething
echo $something
end
function showsomething
set something 1
echosomething
end
```

However, with
```
function echosomething --no-scope-shadowing
echo $something
end
```
