The $ is just a character in the string. Is there a reason you think it would need to be escaped?

How come the $ does not need to be escaped in this solution?

we are supposed to fix the code!!! NOT write a new one....

Elegant.

This way you ensure the string spans from beginning to the end with just one letter. Otherwise you would match any string with a vowel, for example 'codewars'. Because of the above, your solution wouldn't work with the current test set.

It'll return false, as it wouldn't be a valid tail: make sure that the second argument (tail), is the same as the last letter of the first argument (body)

smepple 119 Style...disclaimer number could change anytime..!!! :)

What if tail.length > 1?

this is the best

Love it!

Wow, this is a clever way to use the send mehtod!!!

That is the splat operator - in this context - used for array coercion. You delve deeper here: https://endofline.wordpress.com/2011/01/21/the-strange-ruby-splat/

It shouldn't be possible to require active_support in my opinion. It's not in the standard library.

Thanks
