Metaprog can be abstruse

[user1234]

Example:

```d
auto genDecimalRanks()
{
     import std.conv;
     auto r = 1;
     auto result = "[";
     foreach (i; 1 .. 11)
     {
         result ~= to!string(r);
         if (i < 10)
             result ~= ", ";
         r *= 10;
     }
     result ~= "]";
     return result;
}

/// like 
[1,10,100,1000,10000,100000,1000000,10000000,100000000,1000000000]
immutable decimalRanks = mixin(genDecimalRanks);
```

It takes much more space and time to write DDOC + the generator 
than the space + time required to write the equivalent explicit 
declaration without comments, i.e "self documenting".

So metaprog is not the panacea, do you think to that before 
"meta-progrogramming", or do you "meta-prog" just because it's 
nice ?
