Placeholders

Detailed Description

Lazy objects that can be used in lazy expressions.

When a lazy expression is evaluated, one usually assigns a value to the placeholders which are then plugged into the expression.

Classes
struct	nda::clef::pair< N, T >
	A pair consisting of a placeholder and its assigned value. More...
