Can we get rid of `main` function, just like python

As above, it will be super cool and we can write statements outside the main function, and we don't need to care about #383 also #385

Several reasons why not:

• It introduces more magic, and I don't want Jou to be a language that does things for you magically. Operating systems expect a function named main() to exist, and they call it when the program starts. That said, the main function is already a bit magical, because a call to _jou_windows_startup() (or _jou_macos_startup) is added implicitly to beginning of main().
• This would lead to weird corner cases and surprises when something runs in a different order than you expected. It would be similar to global initialization order problems in C++, but much worse, since people would be encouraged to use it more than global variables in C++.
• We need compile-time if statements anyway. For example, if you have code that calls _NSGetExecutablePath(), it cannot be compiled on Windows or Linux, because _NSGetExecutablePath only exists on MacOS.

This feature makes sense for many other languages, but IMO not for Jou.

I see.
