Description pancake 2010-07-08 16:47:38 UTC 
In Vala you can do:

var foo = new uint8[10];
foo += 8;

which resizes the array and adds a single value.

But you can't do the same with an array of the same type:

var foo = new uint8[10];
var bar = new uint8[10];
foo += bar;

Given error is:

error: Incompatible operand
error: Assignment: Invalid callback assignment attempt

That would be bad anyway, as the += operator would have two different semantics, appending and concatenating.
Comment 2 zarevucky.jiri 2010-07-21 18:43:13 UTC 
In my opinion, the usage of += for appending is wrong anyway.
Why not just add a bunch of methods to arrays? .append() and .concat() would do nicely.
