Here is a new proposal based on the feedback. For reading variable length data, conceptually it's very similar to the existing `IO#readline(sep, limit, chomp: false) → string`, except that the `sep` is not a String, but typically a byte...ntkme (Natsuki Natsume)
The current `String#unpack` has its signature as: ``` String#unpack(template, offset: 0, &block) ``` The concern for unbounded IO read can be potentially solved by having a `maxlen` option: ``` IO#unpack(template, maxlen = n...ntkme (Natsuki Natsume)
I would like to have ruby add `IO#unpack` and `IO#unpack1` that effectively does both `IO#read(...)` and `String#unpacking(...)` in one call. This can significantly improve the performance of consuming data in a variable-length encodi...ntkme (Natsuki Natsume)
