I think there are many who doesn’t split types and algorithms, and something like Java does/did make it cumbersome plus its standard library doesn’t do it — but the C++ comity adopted STL into the standard library 13 years ago, which is all about separating algorithms from their types, and was actually born out of Alexander Stepanov’s work with graph algoritms, so I was also a little surprised by his generalizations and specifically calling out C++ (twice).
