Class BeginExp

public class BeginExp extends Expression

This class represents a sequence of Expressions. The expressions are evaluated for their side-effects, and the value of the last Expression is the result. A BeginExp may optionally have "compilation options" which can be used to control various compile-time aspects of Kawa, such as warning messages.
