zsh: calling functions within functions

When you write shell functions, it is sometimes useful to call a different function (smaller functions are easier to comprehend). How do you do that though?

You can just call it!

Imagine two functions:

hello() {
    echo "Hello, world"
}

main() {
  echo "Running main..."
  hello
  echo "...Ending main"
}

main

Running main...
Hello, world
...Ending main

Depending on what hello does, you may want a Subshell instead.
