+6.4. Q. Why does Python use indentation for grouping of statements?
+
+A. Basically I believe that using indentation for grouping is
+extremely elegant and contributes a lot to the clarity of the average
+Python program.  Most people learn to love this feature after a while.
+Some arguments for it:
+
+- Since there are no begin/end brackets there cannot be a disagreement
+between grouping perceived by the parser and the human reader.  I
+remember long ago seeing a C fragment like this:
+
+	if (x <= y)
+		x++;
+		y--;
+	z++;
+
+and staring a long time at it wondering why y was being decremented
+even for x > y...  (And I wasn't a C newbie then either.)
+
+- Since there are no begin/end brackets there can be no conflicting
+coding styles.  In C there are loads of different ways to place the
+braces (including the choice whether to place braces around single
+statements in certain cases, for consistency).  If you're used to
+reading (and writing) code that uses one style, you will feel at least
+slightly uneasy when reading (or being required to write) another
+style.
+
+- Many coding styles place begin/end brackets on a line by themself.
+This makes programs considerably longer and wastes valuable screen
+space, making it harder to get a good overview over a program.
+Ideally, a function should fit on one basic tty screen (say, 20
+lines).  20 lines of Python are worth a LOT more than 20 lines of C.
+This is not solely due to the lack of begin/end brackets (the lack of
+declarations also helps, and the powerful operations of course), but
+it certainly helps!
