So I have an array of data...
 struct romanSystemData {
   string digit;
   uint   value;
   ulong  regionIndex;
   ulong  previous;
};

immutable romanSystemData romanSystem[] = [
   {"" ,    0, 0, 0},//0
   {"I",    1, 0, 0},//1 8-7
   {"V",    5, 1, 1},//2 8-6
   {"X",   10, 1, 2},//3 8-5
   {"L",   50, 3, 3},//4 8-4
   {"C",  100, 3, 4},//5 8-3
   {"D",  500, 5, 5},//6 8-2
   {"M", 1000, 5, 6} //7 8-1
];

I'm happy I can use this look up table ...

assert( 10 == find!"(a.digit == b)"( romanSystem, "X").front.value);

Now I'm sure I can use std.algorithm map to convert say a string of characters "IVXLCDM" into an array [1,5,10,50,100,500,1000]

but somehow D template instantiation syntax is flumoxing me.

When I try use find in map!"find!""" dmd whinges like crazy at me.

How do you nest these things?
