Clojure macro that doesn't need space next to it

Trying to create a macro form of Haskell's lambda syntax, I'm pretty close except one last tweak, the / (which should be a \, but can't grumble..) needs a space next to it, is there any way to make it so my macro doesn't need space between it and it's first argument?

for instance:

(reduce (/x y -> x y) [1 2 3])

instead of:

(reduce (/ x y -> x y) [1 2 3])

I suspect this isn't possible, but only way to know for sure is to ask people who know, so what's the word?

No, but if you wanted to do something more ambitious, you could define another macro with-haskell-lambdas that you wrap your entire namespace in. That macro could look through all the forms under it, eg with tree-seq, find symbols of the form /x, and replace them with / x instead.

No. Macros cannot change the lexical syntax of the language. That requires read-macros, which Clojure doesn't have.
