-These naming conventions can become awkward pretty quickly.
+As you can see, these naming conventions can become awkward and inflexible pretty quickly:
+<syntaxhighlight lang="php">
+      var wp1 = 0;
+      var wp1alt = 0;
+      var wp1dist = 0;
+      var wp1angle = 0;
+      var wp1length = 0;
+      var wp1id = "";
+      var wp1brg = 0;
+      var wp2 = 0;
+      var wp2alt = 0;
+      var wp2dist = 0;
+      var wp2angle = 0;
+      var wp2length = 0;
+      var wp2id = "";
+      var wp2brg = 0;

 Before namespaces were used, there were only such "global variables", so whenever some piece of code referred to a variable, it was possible to clash with some other similar or even unrelated uses of the variable (imagine a counter variable).
