 string
 : A series of characters wrapped in double quotes: "Hello, World!".
 quotation
-: A list of elements, which may also contain symbols. Quotations can be be used to create heterogenous lists of elements of any data type, and also to create a block of code that will be evaluated later on (quoted program). Example: (1 2 3 + \*)

 dictionary
 : A key/value table. Dictionaries are implemented as an immediately-dequoted quotation, are enclosed in curly braces, and are represented by their symbol definitions. Note that dictionary keys are symbols and therefore can only contain characters allowed in symbols. The {#link-module||dict#} provides some operators on dictionaries.

+The {#link-module||logic#} provides predicate operators to check if an element belongs to a particular data type or pseudo-type (`boolean?`, `number?`, `integer?`, `float?`, `string?`, `quotation?`, `dictionary?`).
 
 Additionally, the {#link-module||lang#} provides operators to convert values from a data type to another (e.g. {#link-operator||lang||int#}, {#link-operator||lang||string#}, and so on).
