While loop : execute code and THEN check condition

ruby-talk
1

Im sure this was possible in C but in ruby i couldnt find something
similiar.

I want a control structure which will execute the code first and then
check if the condition is true or not. something like

do

something

while (condition)

Although
begin
  ...
end while condition

is the idiomatic way to do this I often write my loops as follows

loop do
   ...
   break if/unless condition
   ...
end

I prefer it even more if my code can be refactored to

loop do
    ...
    return ...
    ...
end

Cheers
