thanks. I've noticed the code,too. And that's what I'm confused: when there
is a create, there is no delete, and I can not find the file under
os.TemDir()
Seems I have to debug the code to find the removing line.

Hello gophers,

`generics` looks like a space ,

Its worth noting that Rust does something similar with the "turbofish"

I personally think this works quite well.
