Why does the following code give a compiler error?

	static int[string] table = ["abc":1, "def":2, "ghi":3];

Error message is:

	prog.d:3: Error: non-constant expression ["abc":1,"def":2,"ghi":3]

How is a literal non-constant?

A limitation of the current implementation.  Associative arrays are built on 
the heap, and you can't currently build things on the heap and have them 
exist at runtime.

The best current workaround is probably:
static int[string] table;
static this()
{
  table = ["abc":1, "def":2, "ghi":3];
}

or if inside a function:

static int[string] table;
if (!table)
    table = ["abc":1, "def":2, "ghi":3];
