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.

Just a further note, there is a reason + is not concatenation for arrays.
does "1" + "1" = "2", or "11"? In some languages, both are possible
outcomes, and which one is used depends on subtle differences in the
context.
With a specific operator to mean concatenation, the intent is clear. I
would recommend you stick to using ~ for concatenation, even for your
own types.
