This now complains about trying to append to an unitialized string, 
which seems reasonable:

15:51 < [Coke]> rakudo: class A {}; class B { has A $.foo .= new }
15:51 <+p6eval> rakudo 142c41: OUTPUT«Use of uninitialized value in 
string
                context␤Use of uninitialized value in string
                context␤===SORRY!===␤error:imcc:syntax error, 
unexpected DOT
                ('.')␤     in file '(file unknown)' line 371␤␤»

Closable with tests.
