Reflection - Standard Library

Developers are often told reflection is bad and should be avoided. However, when reflection can help reduce the amount of code needed to solve a problem, it should be considered. Reducing complexity while preserving maintainability must always be a priority. Reflection can be a tool that helps makes this possible. In this talk I am going to show you the power and elegance of the reflection package.
