What good are top-level functions if they’re unreachable from any script interpreter or management RPC server or other languages’ FFI?

- 4ad 5y agoFunctions are useful because you can call them from your program.

I fail to see why Go-level reflection would be involved in that in any capacity. > What good are top-level functions You can call them? From your go code? Are you saying rust or C can't be because they don't have reflection? That's a strange position.
- erik_seaberg 5y agoWhen I type at a Groovy REPL, an interpreter is using reflection for nearly everything. Same goes for native code that has to use reflection via JNI entry points to call Java. It’s damn useful. At the heart of every debugger is a half-finished reflection API that deserves to be cleaned up and surfaced for language interop and novel kinds of tools.
- pjmlp 5y agoHave a look at D and .NET 5 for compile time reflection. Or in Java's case annotation processors. Yes, not everything gets exposed, but it also does the job.
