Initializing Arrays

[Joseph Bell]

That does indeed work as expected.  The following also works:

celsius[3] temps = cast(celsius[3])[0, 20, 18];

and as I expect the following works okay as well:

int[3] ints = [1, 2, 3];

I find it curious though that

celsius[3] temps = [70,80,90]

compiles cleanly in the global namespace and not in the main function.

Any idea why?
