I'm afk and haven't run a test yet, but it's strange. Consulting the spec at https://go.dev/ref/spec#Package_initialization > The entire package is initialized by assigning initial values to all its package-level variables followed by calling all init functions in the order they appear in the source, possibly in multiple files, as presented to the compiler.
Unless I'm reading this wrong, this would indicate that the variable c should have been initialized before the init function was called, and this should have worked fine.
