Most insightful part for me was this one:<p>&gt; Many variations [he&#x27;s talking about Rust] that seemed like they ought to run the same speed or faster turned out slower, often much slower. By contrast, in C++ it was surprisingly difficult to discover a way to express the same operations differently and get a different run time.<p>This is an insidious pitfall that may earn Rust the &quot;slow&quot; label, akin to what happened to Common Lisp.
