+ Dynamically overloaded functions.
+
+ This is an implementation of (dynamically, or run-time) overloaded
+ functions; also known as generic functions or multi-methods.
+
+ The dispatch algorithm uses the types of all argument for dispatch,
+ similar to (compile-time) overloaded functions or methods in C++ and
+ Java.
+
+ Most of the complexity in the algorithm comes from the need to support
+ subclasses in call signatures. For example, if an function is
+ registered for a signature (T1, T2), then a call with a signature (S1,
+ S2) is acceptable, assuming that S1 is a subclass of T1, S2 a subclass
+ of T2, and there are no other more specific matches (see below).
+
+ If there are multiple matches and one of those doesn't *dominate* all
+ others, the match is deemed ambiguous and an exception is raised. A
+ subtlety here: if, after removing the dominated matches, there are
+ still multiple matches left, but they all map to the same function,
+ then the match is not deemed ambiguous and that function is used.
+ Read the method find_func() below for details.
+
+ @note Python 2.5 is required due to the use of predicates any() and all().
+ @note only supports positional arguments

- Dynamically overloaded functions.
-
- This is an implementation of (dynamically, or run-time) overloaded
- functions; also known as generic functions or multi-methods.
-
- The dispatch algorithm uses the types of all argument for dispatch,
- similar to (compile-time) overloaded functions or methods in C++ and
- Java.
-
- Most of the complexity in the algorithm comes from the need to support
- subclasses in call signatures. For example, if an function is
- registered for a signature (T1, T2), then a call with a signature (S1,
- S2) is acceptable, assuming that S1 is a subclass of T1, S2 a subclass
- of T2, and there are no other more specific matches (see below).
-
- If there are multiple matches and one of those doesn't *dominate* all
- others, the match is deemed ambiguous and an exception is raised. A
- subtlety here: if, after removing the dominated matches, there are
- still multiple matches left, but they all map to the same function,
- then the match is not deemed ambiguous and that function is used.
- Read the method find_func() below for details.
-
- @note Python 2.5 is required due to the use of predicates any() and all().
- @note only supports positional arguments
