Thanks!

One nitpick:

attr_WHATEVER :foo, bar

will generate the methods for 'foo', and whatever the value of bar is. 
But bar is not very likely to have the value :bar, so we should only 
generate the tags for 'foo'.

IOW, skip the arguments that are not Ruby Symbols (don't start with a 
colon). The current implementation treats them the same.

The test example looks a bit odd as well, but I'll comment on that in a 
separate email.
