Detailed Description

template<class E, std::size_t Sz>
class tvmet::XprVector< E, Sz >

Represents the expression for vectors at any node in the parse tree.

Specifically, XprVector is the class that wraps the expression, and the expression itself is represented by the template parameter E. The class XprVector is known as an anonymizing expression wrapper because it can hold any subexpression of arbitrary complexity, allowing clients to work with any expression by holding on to it via the wrapper, without having to know the name of the type object that actually implements the expression.

Note:

leave the Ctors non-explicit to allow implicit type conversation.
