[fpc-devel] += with properties

[Michael Schnell]

+= does work for variables, even Strings.

AFAIR, there already has been a discussion about += and friends for 
properties.

In fact I don't see why the compiler not just generates "x.a := x.a + y" 
from "x.a += y" before doing any code generating, disregarding what x.a 
is. Of course an error message will occur if x.a is not writable for any 
reason.

Thanks,
