"First class" indicates that functions are first class, so that an array of functions can be formed directly; in Nial and dzaima/APL function arrays are a special form that can be applied to arguments to return a list of results. BQN's namespaces don't use a dedicated construction; instead, any block (like a [[dfn]]) with <code>⇐</code> statements returns a namespace reference. | "First class" indicates that functions are first class, so that an array of functions can be formed directly; in Nial and dzaima/APL function arrays are a special form that can be applied to arguments to return a list of results.

"Indirect" indicates that a function array can be produced by taking a member of an array of namespaces that all contain that member, each with its own function value. | "Indirect" indicates that a function array can be produced by taking a member of an array of namespaces that all contain that member, each with its own function value. | ||
