A modern programming language that makes developers happier.

kotlinlang

Since Kotlin 1.3 the `fun main(args: Array<String>)`  function is permited to be simplified as `fun main()` (when the entry arguments are not used).

My suggest is that, when the arguments of the entry `main` function ARE used, the IDE/Compiler may accept just `fun main(args)` , assuming the type of `args` would be `Array<String>` .

I'm not a fan of this one. Currently, both forms of main are still valid function definitions, whereas `fun main(args)` isn't.

I would rather see this done like Cocoa+Swift, where there is no main method (instead, a main file) and if you want the arguments you call `CommandLine.arguments`

<https://developer.apple.com/documentation/swift/commandline/2294816-arguments>

does that mean the CommandLine is a `private val commandLine: CommandLine` in the file?

<@UQ78U3PUM> I'm actually not a fan of that one either. It would probably require a bigger / more invasive runtime wrapper. Not to mention it would have implications like what happens if I change the values of the array and some other function uses it elsewhere. Personally, I like it as it is.

<@UAY4JT9CP> Usage is like:


```print(Int(CommandLine.arguments) == 42)```

<@U10EJRH2L> Not as far as I know. It's just a nicer syntax on top of what we're already doing. It can even be inlined if you're really concerned, but we're not exactly doing kernel code in Kotlin :P
