Dir.foreach not with patterns?

Why does the third one not work as expected? It appears that
Dir.foreach will not work with patterns…

#!/usr/bin/ruby

s = “/etc/host*”

#1
l = Dir[s]
p l

#2
Dir.foreach("/etc") { |d| p d }

#3
Dir.foreach(s) { |d| p d }

#4

This is wasteful

l = Dir[s]
l.each { |f| p f }

Use Dir.glob.

You don’t need two lines, though – you can do this in a way that’s actually
shorter than #3:

Dir[s].each {|f| p f}
