> There's something more constricting about there being one function to bootstrap everything than there is about one file.

As someone who basically started coding with C I feel the other way around, unsurprisingly. Even in scripting languages when I write something non trivial I tend to encapsulate everything in functions and then have a `main()` call at the bottom of the file. I think it's one of the things python got right with the `if __name__ == "__main__":` idiom that lets you import any script in a REPL to test individual methods for instance.

(Although the actual syntax of `if __name__ == "__main__":` is IMO utter trash and it amuses me that a language so obsessed with getting rid of symbols and looking like pseudocode decided that such cumbersome, obtuse and ugly looking boilerplate was just fine.)
