No, not at all, only if you need it, and then beware that it can mask 
differences between CPython and IronPython.

The difference in this case is that IronPython has special-cased the 
"from __future__ import whatever" caper -- there is no module called 
__future__ in IronPython. Note the different error messages below:

| >>> from __future__ import somerubbish
| Traceback (most recent call last):
| SyntaxError: future feature is not defined: somerubbish (<stdin>, line 1)
| >>> from sys import somerubbish
| Traceback (most recent call last):
|  File , line 0, in <stdin>##13
| ImportError: Cannot import name somerubbish
| >>>

HTH,
