Is there some lisp that has offers nearly as powerful and fast data processing and tensor algebra facilities like Pandas and Numpy of Python? I would love to use a lisp but am not sure how well are they going to manage with huge 2-3D arrays.

Julia can show s-expressions for an expression I think...sorta what you asked, but not really I know.

If you really want something like pandas + lisp then you probably need Common Lisp and have to dig for some libraries.

I'm a great admirer of Julia, but I doubt it would appeal to those seeking a "true" lisp/scheme. Even if it's has a sane macro system, and much of the same power. You can indeed see s-expressions (search for "s-expression") :

This nice talk mentions a bit on how Julia is (not) a lisp (if I recall correctly):
