/**
 * A step in the construction of the JSON OBJECT function.
 * 
 * 
Referencing XYZ*Step types directly from client code
 * 
 * It is usually not recommended to reference any XYZ*Step types
 * directly from client code, or assign them to local variables. When writing
 * dynamic SQL, creating a statement's components dynamically, and passing them
 * to the DSL API statically is usually a better choice. See the manual's
 * section about dynamic SQL for details: https://www.jooq.org/doc/latest/manual/sql-building/dynamic-sql.
 * 

 * Drawbacks of referencing the XYZ*Step types directly:
 * 

 * They're operating on mutable implementations (as of jOOQ 3.x)
 * They're less composable and not easy to get right when dynamic SQL gets
 * complex
 * They're less readable
 * They might have binary incompatible changes between minor releases
 *
