Throw exception when required file does not exist?

[Jim]

I wanted to do this:

begin
  require 'file'
rescue 
  # 
end

But it does work? Why not?

I know I can do it other ways, but I'm just curious if there's a reason for the behavior.

rescue with no argument will default to StandardError.
What you want is:

begin require 'foods' rescue LoadError puts "not there" end

Ah! Thank you Adam.

But I think I may just be being too lazy to check if the files exists...
