io.LimitedWriter proposal targets zero-copy on the sink side
The day's most concrete item is a proposal to add io.LimitedWriter, mirroring io.LimitedReader so that ReadFrom implementations can recognise a byte cap on the destination and keep splice or sendfile fast paths intact. A second proposal in the same tracker asks fieldalignment to reorder struct fields at compile time rather than as a lint suggestion, which is a more invasive idea and likely the more interesting thread to watch. Around the edges, the usual crop of concurrency and slice explainers, plus a short video reminding everyone that Go exists because a C++ build once took forty-five minutes.
