### Overwriting
```vim
function f1()
echo "f1"
endfunction
function! f1()
echo "f1 overridden"
endfunction
```
If you define two functions with the same name, Vim will throw an error complaining that the function `f1` already exists. To overwrite the previous function with the same name, add a `!` after the function keyword.
