Incorrect error for &ref operator

[Lexikos]

"Unknown operator use" is shown when the ref operator is not being passed as a parameter, but this is perfectly valid:

a := &b  ; & has a red squiggly
MsgBox a = &b  ; 1

I also get a warning that "Variable 'v' appears to never be assigned a value" in cases like the following, but it seems to come and go after making unrelated modifications to other files.

r := &v
%r% := 1

I assume that if you recognize &v as the ref operator, the warning will also go away.
