Should auto concat work with new lines?

[iseahound]

I think that some programmers might be under the impression that code without commas at the end work like this:

Code: Select all

() => (
   fn(1) ; missing end comma
   fn(2)
)

but in reality, it's just returning the result of fn(1) concatenated with fn(2). Harmless?

working example

Code: Select all

MsgBox (() => (
   word("splish")
   word("splash")
))()

word(text) {
   return text
}

I’m not at a computer but I’m surprised your example works… I think your parentheses are messed up a bit because you’re trying to call the return value of MsgBox rather than calling your anonymous fat arrow function.

Well it works fine in Javascript

Code: Select all

alert((() => 'hello world!')())

Well, in your JavaScript example, you have the parentheses in the correct spots to actually call the anonymous function…

[iseahound]

Code: Select all

alert((() => 'hello world!')())

is equal to:

Code: Select all

MsgBox((() => 'hello world')())

I omitted the parenthesis in function call syntax:

Code: Select all

MsgBox (() => 'hello world')()

It can be a bit confusing because of the significant whitespace

That is confusing. I made an assumption that the first open parenthesis was for the MsgBox but apparently due to the space it is not.

@iseahound, I think this is the most sensible behaviour for line continuation. It is not clear what you expect, or wish should happen.

There must be no space between the function name or expression and the open parenthesis which begins the parameter list

I believe this has always been the case, also in v1.
