What do we think about this:

nuller = ()=>; // CF: fine; Lucee: Syntax Error, Invalid Construct on line 2

writeDump([isNull(nuller())])

https://trycf.com/gist/a2d193ecb21c454dbe13d932c6c99c61/lucee5?theme=monokai And, yes, I did actually write code like that. Well actually it was

nullValue = (()=>)()

, but it's a similar issue.

Do you know what other languages support lambda's in that manner. empty I know JavaScript didn't when I just tried.

nuller=()=>; /*errors*/
nuller=()=>{}; /* doesn't error */
nuller=()=>log; /* doesn't error */

@Adam Cameron That syntax smells fishy to me. Why not just use

javaCast("null", "")

? It works in all flavors/versions of CF just fine and I think it's a lot easier to understand.

I think I have a ticket for that

@dswitzer oh I was not using the code. It just cropped up as I was messing around. I am fully aware of

javaCast

and that's what I actually used; just I have always found it dead clunky, and there's precedent about the place for using a

nuller

function to effect the same thing. That got me thinking about exactly how much of the arrow function I actually needed to pull it off, as it were. And @Michael Schmidt yeah, I started with the second of those options, but then wondered why I should need the function body when a short-hand arrow function simply returns the value of the expression. And nothing is an expression (of sorts). I can see no reason why it oughtn't work, even if it's not exactly terribly clear code. Cheers for the ticket URL, @bdw429s. And TIL

nullValue

is a thing in Lucee's CFML. I might use that instead of the

javaCast

approach. No need for cross-compat in my situation.

Uh oh, time for you to read all the Lucee release notes since Railo 2 🤣

in my defence... I have only been using Lucee for 2yrs. Ahem.

modern syntax is ugly AF

Wow didn't know CF had this: https://helpx.adobe.com/uk/coldfusion/developing-applications/the-cfml-programming-l[…]/using-arrays-and-structures/populating-arrays-with-data.html Not sure how useful it would actually be, but it's interesting.
