This may be similar to Enumerable#inject.

This is just bizarre as something to put into Core Python; however,
given that Ruby ships with RDoc, which gives you the RDoc templating
engine, you have something like this already.

> (ruby does/has?)5 PEP 318: Decorators for Functions and Methods

Ruby has this implicitly, because its object model is far more
consistent. The only thing that may improve this is an RCR that
makes it easier to deal with custom decorators by having def return
the Symbol of the method name. Probably :)

This basically introduces popen.

I think that BigDecimal handles this just fine. Note as well that
with the Rational class (require 'rational'), you get support for
real rational numbers. If you add 'mathn', you get full support
including with division, etc.

  require 'rational'
  Rational.reduce(22, 7)    # => Rational(22, 7)

  require 'mathn'
  "%0.9f" % [ 22 / 7 ]      # => "3.142857143"
  (22 / 7).class            # => Rational

BigDecimal works with Numerics, BigIntegers, and Floats, I think.

Not needed.

I don't think that this is needed.
