I've read that Ruby has inherited many features from Lisp.
What features does Ruby have that likely have a Lisp heritage?

This is a good read: http://www.randomhacks.net/articles/2005/12/03/why-ruby-is-an-acceptable-lisp
And lambdas are a direct parallel: http://snippets.dzone.com/posts/show/6770

Lambdas, continuations and list comprehensions are probably the top three.

http://www.ruby-forum.com/topic/89416 has a few ways. Not as pretty as Python's, but they're there.

Those aren't list comprehensions as the term is normally used. They're methods that operate on the list with a lambda. Which is still a lispy thing to do — they're just not list comprehensions.

There are no first class continuations in Lisp. They are in Scheme, which is a variant of Lisp.

There are no list comprehensions in Lisp, either, unless you count the LOOP macro of Common Lisp. (Or one of the innumerable comprehension macros that everybody writes themselves.) I think you mean "Higher order functions".

Vijay: Scheme is-a Lisp.
