// Run-time support for vector-oriented operations in C++-compiled scripts.
// The scope is unary (including appending), binary, and conditional
// operations. It does not include operations common to other aggregates,
// such as indexing and explicit coercion (but does include low-level
// coercion needed to support unary and binary operations).
