[Swift-devel] New syntax for appending to arrays

[Jonathan Monette]

I guess my question would be what would a look like?  What if this was called.

int a[];
int b[];
a=[1,2,3];
b=[4,5,6];

a+=b;

Saying append makes me think that a+=b would result in something like:

[1,2,3[4,5,6]]

Is this the case?  Or would it be [1,2.3,4,5,6].  In python this is called extend while the first is called append.

So are we talking about an extend operation or append operation?
