• I am zah on github.
• I am zahary (https://keybase.io/zahary) on keybase.
• I have a public key ASB3c8AUGb_cjAv7wosU_183YlSZimg7ZYG9rV2H3tdSdwo

To claim this, I am signing this object:

Chunked responses

The chunked responses were originally suggested and discussed in the first network spec PR: ethereum/consensus-specs#1158

Here are the relavant bits from a possible spec:

Response -- After receiving a request, the responding party MUST reply on the same stream within 10 seconds with a response code, followed by the contents of the response.

Here's the canonical TOML example from the TOML README, and a YAML version of the same. Which looks nicer?

# These two are semantically equivalent:

proc makeIterator(x, y: int): Irerator[int] =
  result = iterator(): int {.closure.} =
    yield 1
    yield 2
    
iterator makeIterator(x, y): int =
  yield 1
