The library provides a class called object, which encapsulates a valid Python object and provides a similar interface to Python's.

object operators

The first challenge was to provide support for object manipulations using a Python-like syntax, mostly in the form of operator overloads:



y = x.foo

y = x.attr("foo");

x.foo = 1

x.attr("foo") = 1;

y = x[z]

y = x[z];

x[z] = 1

x[z] = 1;

y = x[3:-1]

y = x.slice(3,-1);

y = x[3:]

y = x.slice(3,_);

y = x[:-2]

y = x.slice(_,-2);

z = x(1, y)

z = x(1, y);

z = x.f(1, y)

z = x.attr("f")(1, y);

not x


x and y

x && y

object conversions

object has a templated constructor which can be used to convert any C++ object to Python using the same underlying mechanisms used for the arguments to call<>.

If an object instance is created without any arguments to the constructor then this instance holds the value None.
