Initial (inocmplete) SSA implementation
Some dead code elimination
Correct ssa for while and block with break and next
Typo
Oops, missing files. Hnadle break and next inside ifs.
Merge branch 'master' into ssa
Correct SSA transformation for break and next: use correct variable indices
Started implementing NoReturn
Merge branch 'master' into ssa
Merge branch 'master' into ssa
Removed Nil#method_missing
Merge branch 'no_return' into ssa
Workaround for Hash#[] until we treat NoReturn in if branches
Marked one spec as pending
Fixed Rakefile
Added hash spec for type inference
Merge branch 'master' into ssa
