Hi Mark,
Smells similar to how Matlab passes multiple return arguments. The []
give the feeling that it is an array, which I like, but I'm not too
keen on accessing the elements by index. Following is an alternate
suggestion for how to use the return arguments:
[Integer foo, String bar] = doSomething();
Better yet, if we could infer types then:
var [foo, bar] = doSomething();
also, one could ignore return arguments if not required. For example:
[null, String bar] = doSomething();
or [, String bar] = doSomething();
I think it's important to package the return arguments, for clarity
sake. As such, I would be uncomfortable with:
Integer foo, String bar = doSomething();
Cheers,
Jason
