Const

trait Const[T <: Txn[T], +A] extends Expr[T, A]

A constant expression simply acts as a proxy for a constant value of type A. Its event is a dummy (constants never change), and the value method does not need to use the transaction. String representation, hash-code and equality are defined in terms of the constant peer value.
