Go's Multiple Return Values vs. Tuples: Historical Rationale from Developer Discussions and RFCs

Introduction Go's decision to favor multiple return values over a native tuple type is a cornerstone of its design philosophy, yet the historical rationale behind this choice remains underexplored. This article delves into the primary sources—early Go snapshots, developer communications, and RFCs—to uncover the mechanisms driving this decision. By examining the causal chain of design choices, we reveal how Go's focus on simplicity, explicitness, and error handling shaped its approac
