[go-nuts] Reflecting on large objects

Hi there, I have a function that needs to introspect on the types of
elements in a []interface{} slice. The interface{} values may be either
pointer-to-huge-struct or huge-struct values. That is, it is really
[]MyBigStruct or []*MyBigStruct. For background, sometimes it is more
efficient to inline big structs in the slice to reduce GC burden.

How can I efficiently determine which element type is present in a
[]interface{} slice? Using reflection naively may cause the large struct
values to be rewritten on the stack multiple times, which I must avoid.
