lazy evaluation with autoload vs require in ruby ?

Question

With my code I'm using autoload for lazy evaluation so I can load the program faster and load the files when needed, I'm not seeing so many people using it, but with Thin project I noticed autoload has been used widely, anyways just wanna know if there is any risk to use it .

Answer 1

autoload is not threadsafe and will be deprecated in the future versions of Ruby. Here is the proof by Matz (creator of ruby).
