The article lists several configuration languages and highlights their shortcomings. The author shares personal frustrations with each format, ultimately revealing the creation of their own language, MAML, which aims to address these issues.

Deep recursion in Go can lead to stack exhaustion, especially in inherently recursive problems like calculating Fibonacci numbers. The lack of tail call optimization in Go exacerbates this issue, making it critical to implement safe limits on recursion to prevent crashes. The article also discusses real-world implications of deep recursion, particularly in parsing recursive data formats such as XML.
