ullrcorners: draw corners on the upper left and lower right sides of a word

The package ullrcorners provides a command to surround a word or a sequence or words by small corners on the upper left and lower right sides. The typographical convention is inspired by Mastering Regular Expressions, by Jeffrey E. F. Friedl (O'Reilly Media, 2006), where it is used to delimit regular expressions.
