For people learning the language, it's not like they can type atilde character into the documenation search and get results. Same forthe other operators. I suppose if one thinks to search for the word'operators', one would get there eventually. I remember how thrown I was years ago when I first tried ^ in PHP,having first learned good ol' MS-DOS BASICA years ago, and thinkingthat I was raising x to the power of y. :-) Andrew PS - For kicks, I just searched for the word 'tilde' and it returnedthe delete() function. :-O
