+1 on all the stuff you said, with one minor exception.  Pyrex-the-language 
is often unpythonically ugly and verbose at present.  If Python had an 
official syntax for optional static type declaration, Pyrex's syntax could 
be aligned with that, and that would at least eliminate most of the inline 
'cdef' ugliness, leaving only C type declarations and Python property 
declarations as the main syntax issues to be resolved.  (Maybe by using 
something like the 'ctypes' API, and having the compiler recognize that 
API, such that C is directly callable from Python anyway, so compiling or 
interpreting Python makes no difference to ability to access C...  but I 

Of course, this would take some effort from the core developers, especially 
Guido, to consider the various syntax needs and formulate official 
solutions.  But if it were done, the Python-vs.-Pyrex distinction could 
fade away altogether, replaced with the meme, "just add type declarations 
to slow parts, and tell Python you want the module compiled to C."

IOW, if Pyrex is merely the name of a compiler, not a separate language, 
then our master plan for world domination is complete.  :)
