Question: Reg. Parameter type of OCFWriter Append function

[kishaningithub]

Context

I see the OCF Writer append function has the signature

func (ocfw *OCFWriter) Append(data interface{}) error

Inside this we are having a reflection based code to ensure this is of a slice type

goavro/array.go

Line 213 in 9f4e906

return nil, fmt.Errorf("cannot create []interface{}: expected slice; received: %T", datum)

Curious Question

Why not change the parameter type to []interface{} ?

I am not aware of a compelling reason, but it does seem to be working. Have you discovered a bug that needs some attention?
