    public void apply(CallContext ctx)
     throws java.lang.Throwable

    Description copied from class: Expression
    Evaluate the expression. This is named apply rather than eval so it is compatible with the full-tail-call calling convention, and we can stash an Expression in CallContext's proc field. FIXME - are we making use of this?

    Overrides:

    apply in class Expression

    Throws:

    java.lang.Throwable
