Hello world!

After weeks of development, lhc is finally able to interpret Hello World!

david@desktop:lhc$ cat HelloWorld.hs
module Main where
main = putStr "Hello world\n"
david@desktop:lhc$ ghc -O2 -fext-core HelloWorld.hs -c
david@desktop:lhc$ lhc build HelloWorld.hcr > HelloWorld.grin

Hello world
Node (Aliased 251 "ghc-prim:GHC.Prim.(#,#)") (ConstructorNode 0) [Empty,HeapPointer 263]

Supported primitives include: indexCharOffAddr#, newPinnedByteArray#, *MutVar, *MVar.

Exceptions are currently ignored and the heap is never garbage collected. However, since I'm evaluating the GRIN (as opposed to translating it to LLVM or C), adding these features should be easy as cake.
