    i.e.: cmake -L rpc will run all RPC label-tagged tests, etc. arbitrary mapping.

    TIL: cmake labels on test targets, so you can do cmake -L <target> which can be any string! woah.

    vs... doing a auto x = unique.. auto raw = x.get() return raw->future_foo().then([x = std::move(x)]{}); how to find the spec if unique underlying pointers are invalidated.

    c++ twitter: are the pointers inside a unique_ptr<> invalidated on a std::move. Trying to see if bug. Imagine this. auto x = unique_ptr.. return x->future_foo().then([x = std::move(x)]{}); all trivially constructible types have type cast for std::move, so it might be fine...

    What a waste to only use one buffer. I use 3x buffers on that wouldn't be possible without 80 chars per line. So little information density otherwise

    What value does “maybe Latinos are bad” or “perhaps we should be shooting each other more” add to a tech business? “Diversity of thought” is a red herring waved around by basic ass cis-het white dudes who don’t have any added value besides being exhaustingly contrarian.

    Frankly, this nothing to write home about with 3 out of 4 instructions being not eliminated stack manipulation instructions (what?). It's a different tradeoff: by storing end pointer rather than size, you make size() worse but end() better. Since iterator-based stuff is ...
