Ruby

When a error is raised in some class methods of Dir, the backtrace is as if the user called Dir.open.

$ ruby -e 'Dir.foreach {}' Traceback (most recent call last):	2: from -e:1:in `<main>'	1: from -e:1:in `foreach' -e:1:in `open': wrong number of arguments (given 0, expected 1) (ArgumentError) $ ruby -e 'Dir.foreach(nil)' Traceback (most recent call last):	2: from -e:1:in `<main>'	1: from -e:1:in `foreach' -e:1:in `open': no implicit conversion of nil into String (TypeError) $ ruby -e 'Dir.foreach("not_exist")' Traceback (most recent call last):	2: from -e:1:in `<main>'	1: from -e:1:in `foreach' -e:1:in `open': No such file or directory @ dir_initialize - not_exist (Errno::ENOENT) 

The last line of the error message should be -e:1:in `foreach': ... like IO.foreach

This occurs in following methods:

• Dir.foreach
• Dir.entries
• Dir.each_child
• Dir.children
