[pLog-svn] This is not fair

It actually doesn't mean anything at all in terms of changes to the
current code, but I was planning to use some of these new features to
make our code lighter and easier to read.

For example as Mark has already pointed out, we could use __get and
__set to "magically" get rid of of most the getter and setter
functions of our database objects, or implement the ArrayIterator
interface for the PDbResultSet class so that we can operate on
database result sets as if they were arrays (so that we can use them
in foreach() loops, access members directly via [], count them with
count(), etc) But in some cases using these "nicer" ways also means
that code is twice as slow to run, or even in some cases an order of
magnitude slower.

Which is why I think it is not fair :) It's not fair for developers
who know how to use these things to develop simpler code (we want nice
AND fast code!), and it's not fair to PHP as a platform either,
because it just means that people will never really use these methods
if they're so slow, and we'll be stuck with code that looks like it
belongs to the 20th century...
