I have the following code, I am attempting to initialise a variable
with a dynamic array. Should the code compile or are lines 6 and 7
just wrong?
test.d
------
import std.stdio;
void main() {
auto numbers1 = [ 1, 2, 3, 4]; // ok, static array int[4]
int[] numbers2 = ([ 1, 2, 3, 4])[]; // ok
auto numbers3 = [ 1, 2, 3, 4][]; // Doesn't compile
int[] numbers4 = [ 1, 2, 3, 4][]; // Doesn't compile
writefln(typeof(numbers1).stringof);
writefln(typeof(numbers2).stringof);
}
C:\>dmd test.d
a.d(6): semicolon expected following auto declaration, not '['
a.d(7): semicolon expected, not '['

You're not using correct syntax. The first problem line, auto numbers3 = [ 1,
2, 3, 4][];, doesn't work because you forgot a comma. I think you want auto to
be evaluated as int[][], however, you have two arrays without a comma
seperator. It should be like this:
auto numbers3 = [ 1, 2, 3, 4], [];
The second line has the same problem, as well as it's improperly declared. It
should be declared as int[][].

I was trying create a dynamic array of ints in the same way that
"hello"[] creates a dynamic array of chars. Maybe I'm mixing up array
and string syntaxes?

It's implicitly castable to a dynamic array (I think). Just don't use
auto (isn't that "feature" annoying?):
int[] numbers = [1, 2, 3, 4];

Thanks, maybe I've been (ab)using auto too much.

No you haven't; that's a perfectly clear use of auto. It's a language
issue that needs to be addressed.

Sorry, that's entirely wrong. First, he wants an int[]. Second, this is
just using the comma operator. It would assign [] into numbers3 (if it
compiled, which I don't know).
