// of the operation. They do not require additional storage and are
// materialized as needed.

// do not use DerivedAttr for things that could not have been stored as
// Attribute.

//
// ## Special placeholders
//
// Special placeholders can be used to refer to entities during conversion:
//
// * `$_builder` will be replaced by a mlir::Builder instance.
// * `$_ctxt` will be replaced by the MLIRContext* instance.
// * `$_self` will be replaced with the derived attribute (value produces
// `returnType`).
