GoLang中更严格的编译选项

Question

Is there an option in golang to fail build if a function returns a value and the returned value is not used? For example, I want an error / warning when we have:

func abc() error

and it is called without an lvalue as:

abc()

EDIT: This is not for errors alone but for return values in general.

Thanks

This is not about the compiler being strict or not. The Go Language Specification allows calling functions and methods without using their return values.

You won't see any compiler options that will stop the building process on use cases which do not violate the lang spec.

What you want may be created or may already exist as an external tool, but not in the Go compiler itself.
