| 21 | 3 # A compatibility layer for Python 2.5+. This is what lets test.py |
| 4 # run on all versions of Python starting with 2.5, including Python 3. | |
| 5 | |
| 6 # A few notes regarding some compatibility-driven peculiarities | |
| 7 # in the use of the language that can be seen in all modules: | |
| 8 # | |
| 9 # * Except statements never specify target; instead, when needed, | |
| 10 # the exception is taken from sys.exc_info(). Blame the incompatible | |
| 11 # syntaxes of the except clause in Python 2.5 and Python 3 and the lack | |
| 12 # of preprocessor macros in Python of any version ;P. | |
| 13 # | |
| 14 # * Keyword-only parameters are never used, even for parameters | |
| 15 # that should never be given in as arguments. The reason is | |
| 16 # the laziness of some Python developers who have failed to finish | |
| 17 # implementing them in Python 2 even though they had several years | |
| 18 # of time and multiple version releases to sneak them in. | |
| 19 # | |
| 20 # * Abstract classes are only implemented for Python 2.6 and 2.7. | |
| 21 # ABC's require the abc module and the specification of metaclasses, | |
| 22 # but in Python 2.5, the abc module does not exist, while in Python 3, | |
| 23 # metaclasses are specified using a syntax totally incompatible | |
| 24 # with Python 2 and not usable conditionally via exec() and such | |
| 25 # because it is a detail of the syntax of the class statement itself. | |
