Operator Overloading + / ~

[Martin Tschierschke via Digitalmars-d-learn]

Just a thought it might be useful for cut-n-paste when porting 
code:

Would it be possible to define an operator overloading for 
'+'-Operator for strings to work as append? (like ~).
I understand, that '~' is in general a better choice than '+', so 
this is of more theoretical interest.
It is clear to me, that when I define my own string type this is 
possible.
