I've been following this discussion on and off for a while, but still fail to see how SI units, factors or the like are a use case which is general enough to warrant changing the language.
There are packages available on PyPI for dealing with this in a similar way we deal with decimal literals in Python: C extension: https://pypi.python.org/pypi/cfunits/ http://pythonhosted.org/cfunits/cfunits.Units.html (interfaces to the udunits-2 lib: http://www.unidata.ucar.edu/software/udunits/udunits-2.2.20/doc/udunits/udunits2.html) Pure python: https://pypi.python.org/pypi/units/ IMHO, a literal notation like "2 m" is more likely related to a missing operator which should be flagged as SyntaxError than the declaration of an integer with associated unit. By keeping such analysis to string to object conversion tools/functions you make the intent explicit, which allows for better error reporting. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Experts (#1, Aug 27 2016) >>> Python Projects, Coaching and Consulting ... http://www.egenix.com/ >>> Python Database Interfaces ... http://products.egenix.com/ >>> Plone/Zope Database Interfaces ... http://zope.egenix.com/ ________________________________________________________________________ ::: We implement business ideas - efficiently in both time and costs ::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
