My Ruby version is: ruby 1.9.3p125 (2012-02-16) [i386-mingw32]

I found that the 'rescue' modifier can not be used in 'require', for example:

require 'not_exist' rescue require 'set' # this will raise a LoadError

I must write a begin/rescue block to do this:

begin
require 'not_exist'
rescue LoadError
require 'set' # this is ok
end

I don't know if it is a bug, I think a one-line require/rescue may be good idiom.

'rescue' modifier and 'rescue' clause with no exception classes catch only StandardError and its subclasses.
LoadError can't be caught.
