drop-quoteclj
(drop-quote sexp)Convert (quote (a b c)) to (a b c).
Convert (quote (a b c)) to (a b c).
non-coll?clj
(non-coll? t)Is a given simple-type a non-collection?
Is a given simple-type a non-collection?
patterncljmacro
(pattern sexp)Parse a provided pattern s-expression into a function that checks each element and sub-element of the form as a whole predicate. Makes semi-smart decisions about using let-bindings to avoid re-accessing the same value multiple times, adding type hints to rely on interop, and handles the complexities of the pattern DLS.
Returns a map or nil. If the provided pattern uses bindings, the map will
have the bindings as keys.

Makes semi-smart decisions about using let-bindings to avoid re-accessing the same value multiple times, adding type hints to rely on interop, and handles the complexities of the pattern DLS. Returns a map or `nil`. If the provided pattern uses bindings, the map will have the bindings as keys.
read-dispatchclj
(read-dispatch sexp _form _retval)Same as [[simple-type]] except that :symbol and :list provide hints about
their contents: :symbol can be refined to :pred, :binding, and :rest, and :list
can be refined to :quote. A refinement can be skipped by adding the metadata
:spat/lit.

read-formcljmultimethod
Implementation of the main logic of pattern. Requires form and retval
symbols to be provided to allow for recursion.

(simple-type sexp)Because Clojure doesn't have this built-in, we must do it the slow way: take an object and return a keyword representing that object:
nil -> :nil
true/false -> :boolean
\c -> :char
1 -> :number
:hello -> :keyword
"hello" -> :string
hello -> :symbol
{:a :b} -> :map
#{:a :b} -> :set
[:a :b] -> :vector
(1 2 3) -> :list
:else -> (type sexp)
