Why should you avoid the then keyword in Ruby?

Question

It\'s mentioned in several Ruby style guides that you should \"Never use then.\" Personally, I think the \"then\" keyword allows you to make code denser, which tends to be

Answer 1

If I remember correctly, then is just one of the delimiters to separate the condition from the true part (semicolon and newline being the others)

if you have an if statement that is a one-liner, you'd have to use one of the delimiters.

if (1==2) then puts "Math doesn't work" else puts "Math works!" end

for multi-line ifs, then is optional (newline works)

if (1==2) 
    puts "Math doesn't work" 
else 
    puts "Math works!" 
end

Could you post a link to one of the style-guides that you mention...
