```


### Expected Output

```text
echo sometemplate
     ^ --> here
> def 5:5 
def     skTemplate      main.sometemplate       template (): auto       ...\main.nim        3       9       ""      100

echo varalias
     ^ --> here
> def 9:5
def     skTemplate      main.varalias   template (): auto       ...\main.nim        7       9       ""      100
```


### Known Workarounds

_No response_

### Additional Information

It works as expected in `--v2` but not in `v3`, `v4`.
