https://stackoverflow.com/questions/5105482/compile-main-python-program-using-cython seems to indicate that (just like a C-program) you need to jump through hoops to get things running.
Being used to simply prepending "#!/usr/bin/python" I am wondering if there is a shebang wrapper that does The Right Thing. I am thinking something like:
#!/usr/bin/cythonwrapper
print "Hello world"
where cythonwrapper checks if the cached file is newer and if not converts the script into C, compiles it, put the compiled file into a cache and runs it.
/usr/bin/cythonwrappereven exist?
