With a firm grasp on its capabilities, you can make write effective, consise, readable and maintainable code all at the same time. By staying consistent, you reduce the amount of special cases that need to be remembered. Reducing the total number of lines of code you write is a good way to avoid documentation, and avoid giving bugs a place to hide.<p> @@ -646,7 +660,7 @@ If you get some free time, and you haven't read them: do so, you might learn som <address><a href="mailto:sabre@nondot.org">Chris Lattner</a></address> <!-- Created: Tue Jan 23 15:19:28 CST 2001 --> <!-- hhmts start --> -Last modified: Mon Oct 1 15:33:40 CDT 2001 +Last modified: Sun Jan 20 13:01:02 CST 2002 <!-- hhmts end --> </font> </body></html> |
