"emplace_back"? People actually looked at this and went "Yes, this is a good function name. I understand this perfectly."?

If you realise how it relates to "placement new" then it does kinda make sense. But yeah, not exactly beginner friendly!

Something like construct_back would've maybe been a little clearer. I imagine that would have it's own issues as well though.

Or just `place_back`! Why do they have to be so whimsical?

Maybe they're fans of why's guide to Ruby :)

Though place_back still has the connotation of 'take this thing and put it over there' that emplace_back is actually the opposite of.

Naming things really is hard.

Don’t blindly prefer emplace_back to push_back
