Just to note -- with your pull request #50 now included in GDC, things speed up 
very slightly.  Removing the const from the Julia value code, results become 
comparable to g++ and the C++ implementation (i.e. about 4.3 s for the 'double' 
case).

LDC still produces a faster executable for this particular code, but then, 
clang++ also produces a faster executable than g++.
