> It also states that it's more work for the compiler, stating that the template resolution seems more complex, and suggesting it's likely to bloat compile times. That's a more persuasive point (hard numbers are provided at the end of the article) I take the author's point about the cost of compiling a template, but the benchmark is odd: a thousand functions with a single call to emplace_back(). C++ programmers are (in)famously willing to trade compile-time performance for run-time performance. Complement the compile benchmark with a realistic program benchmark. In a typical program, I would expect emplace_back() to be called many more times than it's compiled.
