"Hello, {name}!"

# Background
While we do have a ["Hello, World!" challenge](https://codegolf.codidact.com/posts/279147), we still don't have one regarding input. So let's do one!
# Challenge
~~Create a program that inputs a variable (must be standard I/O, not function use) then output `Hello, `, the variable and `!` altogether. Shortest submission per language wins!~~
**Bonus**: Use your username as the input.
