I'm trying to write RIFF parser and can't decide what to do with
"container" type. "Container" chunk should hold a header (two
Word32's), a "type" (Word32 like "WAVE" etc) and a "list" of other chunks.
Of course lists can't be used because we have far more than one chunk
types. What can I do with this?
I discovered existentials for myself recently, but those could be too hard
for me yet. It feels like I'm missing something very obvious here.
Thanks for attention.
