I am unable to install Homebrew(<http://brew.sh/>) using the fish command shell (<http://fishshell.com/>) on my Mac. Here is the error I get:

```
$(...) is not supported. In fish, please use '(curl)'.

fish: ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

```

Please suggest!
