Why doesn't this do the same trick?

SomeModule.instance_eval do
  load 'thefile.ext'
end

Can anyone with a bit more insight than me shed some light on this?  This
works:

Foo.instance_eval do
  eval File.read('mod.rb')
end

Foo.instance_eval File.read('mod.rb')

14:48:46 [ruby]: ./load_mod2.rb
MAIN       in main id=134728276 class=Object
Loading... in Foo id=134689816 class=Module
Loading... in Foo id=134689816 class=Module
14:49:50 [ruby]: cat load_mod2.rb
#!/usr/bin/ruby

puts "MAIN       in #{inspect} id=#{id} class=#{self.class.inspect}"

module Foo
end

Foo.instance_eval do
  eval File.read('mod.rb')
end

Foo.instance_eval File.read('mod.rb')
14:49:53 [ruby]: cat mod.rb
#!/usr/bin/ruby

puts "Loading... in #{inspect} id=#{id} class=#{self.class.inspect}"

Kind regards
