What's the right way to :reload and run :main as a single command in GHCi?

Question

Is there a way to chain `:reload/:r` along with `:main` as a single command in GHCi? The goal here is to avoid typing both every time I change something in my other terminal, but to just type ↑Enter.

Accepted Answer

`:cmd` seems to accept string with multiple lines. Therefore you can do the following command.

```
:cmd return $ unlines [":reload",":main"]
```

also you can add following code to `~/.ghci`

```
:def hoge const $ return $ unlines [":reload",":main"]
```

now you can execute `:hoge` in ghci
