Only provide/export 3 functions or so
Right now the Qn.rkt
file is "providing" (like exporting) every single function it defines. I guess this is good for testing, but we can pass on exporting pretty much all of the per-expr-type helper functions. That is, we don't need to export bin-expr->string
, only expr->string
. We can just export the functions that handle Expr
s, along with any helper functions we're explicitly testing.
