You'd be surprised by how much less elegant CL is, right off the bat. Thankfully, however, one can tweak it in so astonishing a way - I still miss parameterize

You'd be surprised by how much less elegant CL is, right off the bat. Thankfully, however, one can tweak it in so astonishing a way - I still miss parameterized types though - that once you realize the nature of your problem, and put in lots of due work, things tend to become easy in the long run; I particularly adore being able to write iterate macros (adding new "for" clauses"). That said, Matlisp is still in a stage of infancy ("research grade"), and while I welcome contributions, it should be noted that it is not yet a replacement for R/Numpy/MATLAB, atleast not for the casual user.
