Hello all.
Originally reported this here:
http://www.ruby-forum.com/topic/1060963

I believe in windows the following should work but fails (should call out to cmd to process it...)

system("ls.exe")
2.3 2.4
=> true

system("@ls.exe")
=> nil

Thanks!
-r
=end

• ruby -v changed from ruby 1.9.2p0 (2010-08-18) [i386-mingw32] to ruby 1.9.3dev (2011-02-09 trunk 30831) [i386-mswin32_100]

Agreed. C lang's System() allow system("@dir"). Therefore ruby's should allow it too.
Plus, This can be reporoduced on trunk. then I've replaced `ruby -v' field.

Roger, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.

Note: ruby 1.8 makes different result. because we changed system() spec at ruby-1.9.

system("@ls.exe")
=> false
