Re: [go-nuts] Introspecting a type

A variable of type [][]Operation has that type and only that type. Your Concurrent and Sequential types are convertible to []Operation, and this is what happens in the assignment. You can probably use interfaces to accomplish what you want. type Operator interface { Operations() []Operation }

Hi John, I don't know what firm realtime means. I did look at GO's GC a bit. I'm not the expert in this, others in my company are. On the question of realtime thread priorities, that is a requirement, as is priority inheritance. For hard realtime systems, you want essentially "unfair"

Re: [go-nuts] How to get explicit receiver of a method through reflect?

The reflection package provides no way to do this. Even if it were possible to do with unsafe (not even sure it is, but maybe?), it would be brittle and tied to an undocumented representation of a function and its captured variables. Instead, use a single-method interface. It's easy to create a

AFAIK the Go playground has IP-based restrictions for when you are in an export-restricted country (like Iran), just like golang.org is not reachable there. The reason being, that US-laws are forbidding it. There are several threads on golang-nuts and github discussing that, which you can probably
