While some of these functions could be useful, I would never think to look for them in package generically named "Util". I would much rather see the functionality here supplied elsewhere (in more specific packages) or integrated to existing modules.
Wow, a top-level package named "Util". That's really handy. And it includes such related functions as "infinity()", "rtrim()", and "appendfile()".
