Alternatively, new values can be allocated and initialized with factory
functions of the form:

	func NewT(v V) *T

For instance, [NewInt](x) returns an *[Int] set to the value of the int64
argument x, [NewRat](a, b) returns a *[Rat] set to the fraction a/b where
a and b are int64 values, and [NewFloat](f) returns a *[Float] initialized
