Summary:                    You cannot overload += or other operators that are
defined as macros in macros/operators.n
Description: 
Because the macro is applied before the user defined operators are applied,
the overload is silently ignored.

++ and -- are overloadable, but cannot be applied to immutable variables
because the macro performs an assignment.

I think it is important to allow an arbitrary function to be called by any
operator, because it allows programs to define mini-languages that operate
among a group of classes.

That being said, this issue should at least be documented. 

The operators effected are:
&&, ||, %||, %&&, %^^, ++, --, +=, -=, *=, /=, <<=, >>=, %=, |=, &=, ^=,
<->, ::=
