I couldn't comment in your blog, so I'll write it here.
I would prefer the following solution:
(let [matrix [[1 0 1]
[0 1 0]
[1 0 1]]]
(simplify `(* 5 (determinant ~matrix))))
with the option of using a macro construct-expression:
(let [matrix [[1 0 1]
[0 1 0]
[1 0 1]]]
(simplify (construct-expression (* 5 (determinant matrix)))))
construct-expression could query the current environment:
