The PDF document sounded interesting and I was tempted to test WPython.
Unfortunately it doesn't compile on my box:
$ make
gcc -pthread -c -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall
-Wstrict-prototypes -I. -IInclude -I./Include -DPy_BUILD_CORE -o

wpython 1.0 is an almost complete replacement for Python 2.6.4 (except for Doc/library.dis.rst, which I'll update later, when I stop adding or changing opcodes).
I have changed the ASDL grammar (in Parser/Python.asdl) so that there's no need to overwrite Include/Python-ast.h, and I've added full support for constants to the AST code (I left Num_kind and Str_kind untouched right now, but I plan to remove them in the next release, since Const_kind is able to hold any kind of constant object).
Now you shouldn't have problems compiling it.
