Note that in tablecloth we have to explicitly omit rows where the value we're filtering by is missing, unlike in other libraries. This is because tablecloth actually uses nil (as opposed to a library-specific construct) to indicate a missing value , and in Clojure nil is not treated as comparable to numbers. If we were to try to compare nil to a number, we would get an exception telling us that we're trying to compare incomparable types. Clojure is fundamentally dynamically typed in that it only does type checking at runtime and bindings can refer to values of any type, but it is also strongly typed, as we see here, in the sense that it explicitly avoids implicit type coercion. For example deciding whether 0 is greater or larger than nil requires some assumptions, and these are intentionally not baked into the core of Clojure or into tablecloth as a library as is the case in some other languages and libraries.
