Yes, JHC doesn't put a large runtime into the executables (and, as a whole 
programme compiler can remove more dead code than GHC can).

Stripping GHC's helloWorld:
-rwxr-xr-x 1 dafis users 377240 19. Okt 13:55 helloWorld

What makes in unusable for me is that it doesn't yet have arbitrary 
precision integers (if that changes, the library problem might step in).
I hope it gets proper Integers and better library support soon, it's quite 
an exciting project.
