[Python-ideas] Ruby-style Blocks in Python Idea

[tav]

Hey all,

I've come up with a way to do Ruby-style blocks in what I feel to be a
Pythonic way:

  using employees.select do (employee):
      if employee.salary > developer.salary:
          fireEmployee(employee)
      else:
          extendContract(employee)

I originally overloaded the ``with`` keyword, but on Guido's guidance
and responses from many others, switched to the ``using`` keyword.

I explain the idea in detail in this blog article:

 http://tav.espians.com/ruby-style-blocks-in-python.html

It covers everything from why these are useful to a proposal of how
the new ``do`` statement and __do__ function could work.

Please note that the intention of this proposal is not to encourage
iteration with blocks -- Python already does this rather elegantly --
but blocks are very useful for more than just iteration as various
Ruby applications have shown.

Let me know what you think.

My apologies if I've missed something obvious. Thanks!
