#define IMP_BRACKET	(		Value,
			Index,
			bounds_check_expr,
			expr
	)

Implement operator[] and at() for C++, and getitem for Python.

The index type is Index and the expression that returns the value is expr. Like the equivalent methods in std::vector, at() performs bound checking; if the bounds_check_expr is false, then a UsageException is thrown. operator[] does no bounds checks, except in debug mode. In Python, bounds checking is always done and results in an IndexException if bounds_check_expr is false.

#define IMP_CONST_BRACKET	(		Value,
			Index,
			bounds_check_expr,
			expr
	)

Value:

const Value at(Index) const;                                   \
  const Value operator[](Index) const;

Implement operator[] and at() for C++, and getitem for Python.

The index type is Index and the expression that returns the value is expr. The value returned is not mutable. Like the equivalent methods in std::vector, at() performs bound checking; if the bounds_check_expr is false, then a UsageException is thrown. operator[] does no bounds checks, except in debug mode. In Python, bounds checking is always done and results in an IndexException if bounds_check_expr is false.
