Subject: Re: functional Ruby equiv to this perl snippet

Here's my attempt to squish that code down even further.

def load_server_list(file_name)
    servers = []
    IO.readlines(file_name).each { | line |
	# Next line assumes input always has newlines
	line = line.chomp!.strip  		# chomp instead of chop
	next if line.empty? || line[0] == ?#	# Use ?# just to be different
	servers << line
    }
    return servers
end

servers = load_server_list(ARGV[0] || "serverlist.txt")
server_count = servers.length
