Functions are great, and I recommend using them - just use them _inside_ the script. For anything but the most trivial scripts I make the main body of the script a function, too, something like this:

#!/usr/bin/env zsh
main() {

}
Just remember the main "$@" at the bottom, otherwise you've got a script that just declares some functions and exits without calling them. :)
 
Only define functions inside your interactive shell when they need to make changes that persist after they exit - like changing directories, or updating variable values, etc.
That would limit their number considerably.

Indeed. As a point of comparison, over the years I've written about a thousand little personal utility scripts that live in my ~/bin directory. I've only accumulated about 50 functions.
