What happened?

This code won't compile:

FUNCTION plusOne(ByRef a As Ubyte) As UByte
  LET a = a + 1
  RETURN a
END FUNCTION

DIM myArray(5) as Ubyte

PRINT plusOne(myArray(3)) : REM Ok. Will increase myArray(3) by 1 and print the result

The code was taken from the docs (irrelevant parts removed).

Error and Warning messages

byref.bas:8: error: Expected a variable name, not an expression (parameter By Reference)
