It's not valid to use an array initializer in an expression; a correct message is now issued.

What is the correct way to re-initialise an array?

uint c[5] = [0,1,2,3,4];

c[] = c.init;

?

Or maybe

foreach(inout uint u; c)
	u = u.init;

if so, it would be nice if there was a shorthand way, like

c[] = c[].init

or something.

The way right now to do it is create a static version of the array initializer, then copy it into the arrays you want to reset.

Ok, so what is the point of the arrays' .init property then?

It actually gives you a null value, because that is the default initializer for [] arrays.

Aha! I thought so, so.. why not turn this:

uint[5] c = [0,1,2,3,4];

into 2 arrays, 1 array 'c', and 1 static array which is assigned to the c's init property (instead of null), so that:

c = c.init;

will then re-initialise the array.

For this:

uint[] c;

init would remain null and

c = c.init;

would be identical to

c = null;

which works doesn't it?
