Dumping context.Context() doesn't show useful info

[rskumar]

Code:
litter.Dump(r.Context()) where r is a http.Request.

Output

&context.valueCtx{
  Context: &context.valueCtx{
    Context: &context.valueCtx{
      Context: &context.valueCtx{
        Context: &context.valueCtx{
          Context: &context.valueCtx{ // p2
            Context: &context.valueCtx{
              Context: &context.cancelCtx{
                Context: &context.cancelCtx{
                  Context: &context.valueCtx{
                    Context: &context.valueCtx{
                      Context: &0,
                    },
                  },
                },
              },
            },
          },
        },
      },
    },
  },
}

While github.com/davecgh/go-spew does show Values and other properties set in Context.

Does Spew handle contexts as a special case?

[rskumar]

I didn't find any reference to context.Context in their code (any import). So just a quick guess, maybe their introspection throgh reflect giving inner values. I will try later to debug and check their flow.

Litter's default options hide private fields. Tried using litter.Options{HidePrivateFields: false}.Dump(ctx)?

[rskumar]

Tried litter.Options{HidePrivateFields: false}.Dump(ctx) with http.Request Context, and it started spewing values infinitely. I think there may be circular ref which its following and never stops.

That sounds like a bug, indeed. Can you file a separate issue with example code? Thanks!
