Ruby and Python both meet your description quite well. Ruby a bit more so than Python. Ruby refers to the style as Ruby Prose, because it’s meant to be incredibly readable, expressive, and easy to write. I wouldn’t say you should write big code bases in it, mostly because both Ruby and Python are dynamic languages. They both start failing the larger and larger the projects get, not because of speed, but because of typing.

Ruby also has a massive standard library. Things like .permutations() are even included, making Ruby incredibly readable for complex stuff.
