NOTE
Go Reflection
Runtime type/value inspection, settable values, interfaces, tags, and reflection trade-offs.
This is a historical learning note and may contain outdated or incomplete understanding.
The reflect package exposes runtime Type and Value information for generic frameworks such as serializers, validators, dependency injection, and ORM-like tooling. A reflected value must be addressable/settable before mutation is allowed.
Reflection trades static type safety and simplicity for runtime flexibility. Prefer generics, interfaces, or generated code when they express the problem more clearly; isolate reflection-heavy code behind small tested boundaries.
