Multi-line comments

Roc does not support native multi-line comments like /*...*/ in other languages. It's # all the way:

# Line 1
# Line 2
# Line 3

TIP: Many editors provide shortcuts to (un)comment multiple lines at once, like Ctrl+/ in vscode.

Why?

We need to use # for compatibility with unix shebangs. This allows roc files to be run as a script with for example ./myscript.roc.
