SQLAlchemy with Python 3.2: C extensions are not supported?

Question

I've installed SQLAlchemy under Python 3.2.2 and saw e message in command prompt:

C extensions are not supported on this Python platform, speedups are not enabled.
Plain-Python build succeeded.

But in docs:

The C extensions as well as Python 3 builds are supported.

How could it be?

Answer 1

English ambiguity.

{The C extensions} and {Python 3 builds} individually are supported.

{The C extensions and Python 3 builds} together are not supported:

Later in the doc:

Currently, the extensions are only supported on the 2.xx series of cPython, not Python 3 or Pypy

Answer 2

The patch was written before Dec 25 '11 and it's still not implemented almost 2 years later.... boo hiss!
