You should strive for better readability for intended audience in every single program you write. It's like writing prose, really. It's ok to write "notes to self" with words shortened to single letters and strange symbols all around the place. It's not ok to do the same in a report from a meeting.
You should always remember who you're writing for and write accordingly. Hint: you almost never write for the computer.
The "proper" syntax is dumb. I've never considered writing functions to get around it, but seeing this makes me want to contribute some builtins to bash.
