+// The purpose of glz::validate(value) is to use the structural memory for validation
+// rather than validating against an input buffer like JSON
+// Benefits of this approach:
+// - Supports validation of multiple formats by first parsing into the object and then validating the input.
+// - Supports both read/write validation.
+// - Allows this validation to be developed separately from format code, which significantly reduces the amount of code required.
+// Downsides:
+// - For read validation we don't error until after the entire object has been parsed, which forces a copy of data if we're trying to prevent invalid inputs. But, the benefits still often outweigh the costs.
