Detailed Description

template<typename Object>
struct boost::proto::lazy< Object >

A PrimitiveTransform that uses make<> to build a CallableTransform, and then uses call<> to apply it.

lazy<> is useful as a higher-order transform, when the transform to be applied depends on the current state of the transformation. The invocation of the make<> transform evaluates any nested transforms, and the resulting type is treated as a CallableTransform, which is evaluated with call<>.
