Only runs on x86-64 architectures and operating systems. Only runs on POSIX-compliant operating systems. Snow currently requires the experimental GCC version 4.4 Snow also could have benefited from being prototyped in Awk and Sed first. How can you be influenced by "Smalltalk, Python, Ruby and JavaScript", and still end up writing your compiler in C++? Good luck to the author, if this is a first attempt (but compiler writing != language design.)
