Good question. I will add that.
It means that users' convenience comes before my convenience. (I am the programmer in question.)
This means that if there is something I could do to make things easier on users, I do it, even if it is a lot more work for me.
An example is https://git.yzena.com/Yzena/Yc/commit/c9086af225d42b2f125959... . Comments in Yao do not use the `#` character, but I added the shebang to the parser specially so that scripts could be run just like any others scripts.
