I didn't expect a jump in size of that magnitude, but i didn't check for 
it either.

In release builds the size difference is smaller, and the best results 
are with ldc. (-O -release + strip) With ldc the HelloWorld demo is just 
2.4MB (2.2MiB) a 0.2MB increase from the previous release.

For the library itself this is a bit more with a 30% increase in size.
