Does D provide a way to initial;ize an associative array?  I want to use a
static const associative array in a class.  I'm beginning to think I'll have to
drop the const part and use a static initializer instead.

Unfortunately, currently there are no associative array literals. Thus 
you won't be able to create a constant associative array. Walter hasn't 
expressed his mind on it, although there were a number of proposals.

I have considered before the notion of cobbling one together with some inline
assembler (or, more likely, writing a tool to automate such an asm block), but
there's one small problem - from the D Manual page "Application Binary
Interface":

 Associative Arrays
 TBD

Bah! I would like to know when this small piece of documentation could be
completed.

 int[3] a = [ 1:2, 3 ];          // a[0] = 0, a[1] = 2, a[2] = 3
        
 This is most handy when the array indices are given by enums:
        enum Color { red, blue, green };

 int value[Color.max] = [ blue:6, green:2, red:5 ];

The logical jump for me would be:


int[char[]]  foo  = [ "joe":5, "fran":10, "bob":20 ];


However, I don't think it's currently implemented.
