1 Namespace Definitions
2 =====================
3
4 Attributes can be redefined in modules and classes, but this eliminates much
5 of the potential for optimisation. However, names of classes and functions
6 could be restricted to only refer to the same kinds of objects within the same
7 namespace. If redefinition were to occur, or if multiple possibilities were
8 present, these restrictions could be moderated as follows:
9
10 * Classes assigned to the same name could provide the union of their
11 attributes. This would, however, cause a potential collision of attribute
12 definitions such as methods.
13
14 * Functions, if they share compatible signatures, could share parameter list
15 definitions.
16
17 It is easier, however, to regard multiply defined classes and functions as
18 non-constant and to either disallow optimisations or to actually prevent the
19 program describing them from compiling.
