remove page function - r#d

Since at the moment there is no way to 'permanently' delete a page from scripts (see this thread http://www.google.com/support/forum/p/apps-script/thread?tid=31e4f73ae642c2b6&hl=en )  a mechanism is needed for those of us that wish to delete a page and then re-use that same url for a new page (as discussed above). I've written the function below and would appreciate any advice as to whether there is a more elegant way of achieving what I'm trying to do. I can see no (easy/efficient) way of finding out if a given page url has been used so I rely on the fact that renaming a page to a url that is 'deleted' but not 'permanently' throws an error. But this feels wrong - there ought to be a way of checking whether an operation will fail before actually doing it. Any suggestions for a better way of doing this ?

function removePage(page) {   // renames page before deleting it so thet the URL can be re-used   // returns true if successful, false if not   var pageSuffix = 1;   var pageRenamed = false;   var pageName = page.getName();   // pageSuffix check is get out in case error trap fails which would leave us in endless loop   while (!pageRenamed && pageSuffix < 100)   {     try     {       // rename the page before deleting it so that we can keep the original url       // this will fail if the name has been used before - we catch this using the error trap       var page = page.setName(pageName+"-"+pageSuffix);       // if we get here, page renaming succeeded , so set flag       var pageRenamed = true;     }     catch(err)     {         // Tried to rename a page to one that has previously been deleted, so keep trying till we succeed             pageSuffix++;     }   }   if (pageRenamed)   {      page.deletePage();   }   return pageRenamed; }​
