So basically I define a class that behaves like bool, but add compiler specific parameters to make instance of this class 1 byte? On Wed, Jun 26, 2013 at 12:17 PM, Pauli Virtanen <pav@iki.fi> wrote:

In c++, user classes can't inherit from primitive types. Thus spake Bjarne.
Make a memory-layout compatible class (i.e., one with a single npy_bool member), and then cast back and forth as needed?
I somehow doubt that
class Foo { char b; };
assert(sizeof(b) == sizeof(char));
is guaranteed by C++ standards. However, we can just start inserting compiler-specific packing pragmas for those cases where it isn't true.
For safety, however, it's probably best to include the assert statement in one of the routines. The compiler should optimize it away, and it will break scipy test suite if the file is miscompiled.
