Subject: A doubt about the Dir::[] class method

Hi,

I am learning Ruby from the poignant guide and in chapter 4 I came
across the Dir::[] class method in a particular code snippet.

I tried a few variations with the way this method is invoked :
1) Dir::['*d*'].each {|file_name| puts file_name}
2) Dir::[]('*d*').each {|file_name| puts file_name}
3) Dir.[]('*d*').each {|file_name| puts file_name}
4) Dir['*d*'].each {|file_name| puts file_name}

The first call does not work but the remaining three do. I have not been
able to figure out why any one these invocations works/does not work.

Thanks.
