Does Ruby have double interpolation?

Question

ruby

Good afternoon. Does Ruby have double interpolation when typing?

p = "my param"
s = $stdin.gets.strip! # #{p}
puts "Hi #{s} hi!" # Я хочу "Hi my param hi!"

Answer 1

That won't work. Interpolation is just syntactic sugar. You need to run your input through eval.

Answer 2

Then why not
puts "Hi #{p} hi!"

Answer 3

yield, if I understand correctly
