[Python-Dev] ANN: PEP 335: Overloadable Boolean Operators

[Greg Ewing]

exarkun at divmod.com:

> Python's parser is already available, through the compiler module.
> The example given earlier, query("x and y or z"), is relatively
> straightforward to implement as a set of AST manipulations.

But that misses the point, which is to have the expression
blend in seamlessly with the rest of the Python code. Anything
which requires the explicit invocation of a separate parsing
phase prevents that.
