Estes escopos representam "permissões".

No OpenAPI (e.g. os documentos da API), você pode definir "esquemas de segurança".

Quando um desses esquemas de segurança utiliza OAuth2, você pode também declarar e utilizar escopos.

Cada "escopo" é apenas uma string (sem espaços).

 * Second, it is always backed by an array large enough to hold a value for every possible
 * combination of row and column keys. (This is rarely optimal unless the table is extremely dense.)
 * Finally, every possible combination of row and column keys is always considered to have a value
 * associated with it: It is not possible to "remove" a value, only to replace it with {@code null},

## Tipo de Retorno y Filtrado de Datos

Continuemos con el ejemplo anterior. Queríamos **anotar la función con un tipo**, pero queríamos poder devolver desde la función algo que en realidad incluya **más datos**.
