self assignment
 Examples: 
        foo += 12

 Syntax: 
        expr op= expr     # left hand side must be assignable.

 This form evaluated as expr = expr op expr. But right hand side expression
evaluated once. op can be one of: 
        +, -, *, /, %, **, &, |, ^, <<, >>, &&, ||

 There may be no space between operators and =. > 

RTFM?
