Can Go Dynamically Iterate Through a Package Like Python?

Discovering the Secrets of Dynamic Package Iteration in Go

For a newcomer to the Go programming language, navigating its intricacies can be a stimulating experience. This question takes us on a journey to explore the challenges of dynamically iterating through a package.

The questioner, a former Python devotee, seeks to construct a straightforward calculator using Go. As they envision adding new features, they recognize the potential for excessive wordiness if they follow a traditional approach. To streamline the process, they inquire whether there exists a method for discovering and iterating over all the methods within a package.

Upon investigating the Go documentation, particularly the reflect package, they come up short. Unlike Python or other dynamically typed languages, Go employs static typing, which discourages the type of introspection they desire. The compiler restricts the executable to exclusively those functions and variables that are explicitly referenced.

Reflecting on this limitation, the astute observer arrives at a pragmatic solution. By creating an array of objects representing the target types, they can iterate through this array to accomplish their goal. While not quite the dynamic package traversal they had hoped for, it offers a viable workaround that harnesses the power of Go's static typing.
