[mercury-users] Generating small and fast binaries in Mercury

While in general that's true, for a basic hello world program hardly any 
functionality is being used at all. It would be interesting to see a 
break down of how much of the resulting binary is taken up by the 
runtime, the garbage collector and the standard library; particularly 
comparing how much of the standard library is included in the binary but 
never actually called :)

Cheers,

Michael
