[2.1-alpha.8] Static variables can't be initialized as unset

[niCode]

This has been happening since at least alpha-7. I haven't tested any alphas prior to that.

Example:

Code: Select all

; Error: This statement's parameters cannot be unset.
MyFunc()
{
    static var := unset
    var := 'something'
    MsgBox(var)
}

This works on the stable versions. I haven't seen anything to indicate this has been changed either here or in the built-in documentation (that includes alpha changes).

c:=&var:=(x?) also cannot work after alpha.2

@niCode While this is a bug, it would be more efficient (typing and execution) to omit := unset in that example.

Spoiler

Something like static _ := (MsgBox(), unset) would execute only once, but not keep the return value. Also, a static variable can be declared multiple times, or assigned before the declaration. In those cases, it can be meaningful to assign unset.

@V2User That is unrelated, and the code works correctly in v2.1-alpha.8.
