C style array declaration.

[Aedt]

I'm a big fan of betterC. In C, you can initialize an array 
without specifying the length like this
int ia[ ] = {0, 2, 1};

What is the translation of this? Note that int[] is a different 
type than C's arrays. 
https://dlang.org/spec/interfaceToC.html#data_type_compat says 
there are no equivalent to this. What's the workaround?

Also, is it possible to retrieve the pointer of the sequence of 
actual data from std.container.array? If all fails I'd like to 
use this container.
