In practice, you _can_ have initialized static AAs, provided they are 
read-only (which is probably the main time you want to supply 
initializers). The declaration syntax for a read-only AA slightly lacks 
syntactic sugar, but the syntax for usage is perfect:

char[][uint] symTable() { return [2u:"he",4:"ho",6:"hi"]; }

void main()
{
     for (int k=1; k<=6; ++k) {
         if ((k&1)==0) printf("%.*s\n", symTable[k]);
     }
}

BTW, these read-only AAs are great for eliminating case statements!
------------------
char [] a;
switch(k)
{
case 2: a="he"; break;
case 4: a= "ho"; break;
case 6: a="hum"; break;
}
------------------
becomes:
------------------
char [] a = [2:"he"[], 4:"ho", 6:"hum"][k];
------------------
Which is pretty awesome when you have a lot of trivial cases; ought to 
generate better code, too.
