    using CONSTRUCTOR node?

What I mean by "simple" is something that's easy to derive.  Suppose I have
a record with numerous fields of various sizes and I unchecked convert a
constant to it.  Yes, I could write code to convert that into a CONSTRUCTOR
by figuring out what value should be assigned to each field, but that's a
pretty large block of code for a pretty marginal case.
