The attached patch removes the 2-stage initialization feature from the C++ interface classes. I consider it to be bad design since it allows objects to exist in an invalid state. Also it is inconsistent since not all classes have it. It was argued to be a memory management feature, but smart pointers are better suited for that. std::auto_ptr provides the same functionality as the current...

In fact, I think vector cross product is always right-handed. At least I haven't ever seen a left-handed cross-product and Mathworld (http://mathworld.wolfram.com/CrossProduct.html) defines it as being right-handed.

From Physics - Dynamics - Combined Linear and Rotational quantities: "I think something is wrong with the sign since J should produce a greater velocity change if there is both linear and rotational motion, I assume its something to do with the direction chosen for positive rotation."
You are somewhat right there. The root of the problem is that you have mismatched equations for...

I'm creating a PkgConfig builder, which currently works
simply by reading input, substituting variables from
environment and writing output. However, I noticed
that env.subst eats any whitespace from end of input.
Code:
data="foo $CC\nbar$CXX\n"
print repr(data)
print repr(env.subst(data))
Output:
'foo $CC\nbar $CXX\n'
'foo gcc\nbar g++'
As you can see, both variables are...
