+SYNOPSIS
+ mixed to_struct(mixed *|mapping data)
+ mixed to_struct(mixed *|mapping data, struct template)
+ mixed to_struct(struct data)
+ mixed to_struct(struct data, struct template)
+
+DESCRIPTION
+ The given array, mapping or struct <data> is returned as a struct.
+ If a <template> struct is given, the returned struct is of the same
+ type. Without a template, an anonymous struct is returned in case of
+ arrays and mappings and in case of structs <data> is returned
+ unchanged.
+
+ If <data> is an array, its elements are assigned in order to the
+ resulting struct. For an anonymous struct, all elements of <data>
+ are assigned, for a templated struct only as many as fit into
+ the struct.
+
+ If <data> is a mapping and no template is given, the resulting
+ anonymous struct contains all elements from <data> with a string
+ key; the key name is used as struct member name.
+
+ If <data> is a mapping and a template is given, the struct
+ member names are used as keys for lookups in <data>; the found
+ data is assigned to the struct members.
+
+ If <data> is a struct and a template is given, a struct of the type
+ of template is created and all members from <data> are copied to the
+ new struct, which exist in both structs. This conversion is only
+ allowed between a struct and one of its base structs or a base struct
+ and one of its children. Otherwise an error is raised.
+
+ Neither <data> nor <template> will be changed in this process - the
+ result is a new struct value. The actual value of <template> does not
+ matter, only its type.
+
+ Since the returned struct can't be known at compile time, the
+ efun is declared to return 'mixed'.
+
+HISTORY
+ Introduced in LDMud 3.3.250 .
+ LDMud 3.3.344 added the template argument.
+ LDMud 3.3.433 added the conversion from mappings.
+ LDMud 3.3.720 added the conversion of structs into another struct.
