Seems like brackets are optional? What’s the rule here?
System.DebugLog "Hi Mom!"
works as well as
System.DebugLog("Hi Mom!")

If the method returns a value (a function) any parameters passed need to be enclosed in parentheses.
If It is a just a method (no return value) they are optional

Thanks, @Karen.
I wonder where that policy came from? I’ve not noticed other languages that work that way…
I would guess because when you return a value that value not only has to be used (assigned to something) but the return value could be combined with other values before assignment.
Eg
Y = someFunction( x + a + b ) + c
Y = someFunction x + a + b + c
Sorry, I probably wasn’t being clear. What I meant was, are there any other languages where brackets for parameters are optional? I’ve not encountered that before, and only noticed it when looking at others (usually older) Xojo/RB code.
You’d have to ask Andrew Barry - the original design of Cross Basic which has evolved into Xojo
This has been the case forever
I dont know of one
