Subject: Recursive methods allowed in Ruby?

Does Ruby allow recursive methods? For example, in Java you can have a
method call itself, and an example such as the one below will work. When I
try to run the following Ruby example, I get a "stack too deep" error. (Or
did I just make a stupid mistake?)

Thanks,
Krishna

def list_dirs( inDir )
    Dir.foreach( inDir ) {|x|
        print( x )
        if File.ftype( x ) == "directory"
            list_dirs( x )
        end
    }
end

ARGV.each{ |dirName|
    list_dirs(dirName)
}
