[NEW] First hints of cross-platform support. Compiles to Mach-O on Darwin with nasm and gcc.
...
There is no binary assembler support for Darwin yet! I'm not sure when I will dive into the details
of generating a Mach-O binary from Ruby or C.
[MERGED] Binary assembler support. It *should* work on ELF but it needs testing on Linux.

[NEW] Emit x86 code for the mov instruction. Barely works 1/2 the time.
...
The supporting infrastructure includes a C program for reading a
binary blob of x86 code and wrapping it in an ELF executable for Linux
x86. Unsure about getting the data for other sections of the binary
besides .text.

[NEW] while, until, repeat, and break keywords.
...
While and until loops work as in C and Ruby. Repeat loops infinitely
(or until a break is encountered). Break is used to break out of the
innermost loop construct.
