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 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

[kioba]

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

@ki Usage is like:

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

@Ruckus 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
