Golang Diaries: Generics
My coding time this year has been invested in Quamina , an event-filtering library implemented in Go. Just in the last couple of weeks I spotted an opportunity to bring Go’s shiny new generics to bear, and not just anywhere, but for a central data structure.

On one hand, well-written ones catch bugs and maintain a program’s stability, but as the code base grows, a high number of…
