It's never been documented, and you discourage its use, just because
you don't like the syntax that you created? If ${parameter^^} means
upper case, and ${parameter,,} means lower case, ${parameter~~} fits
the theme. What's not to like? Would you rather use ~ in a parameter
expansion to mean something else in the future?
