How to do a one-liner while loop in Ruby using curly braces

Question

I was trying to do a simple one liner while loop in ruby using the curly braces. I was sucessful in the following formats:

while x < 5 do x+=1 end

This is sufficient as a one liner but im not a fan of using do end in one liners. I would like to do something similar to this:

while x < 5 { x += 1 }

Can this be done?

Answer 1

What about this one:

x = 0
x += 1 while x < 5
x 
#=> 5

Answer 2

Instead of this:

x = 0
while x < 5 do
  puts x
  x += 1
end

you could write this:

5.times { |i| puts i }
