                         ^
                         this part will only match a the beginning of a
                         line or an empty string at the beginning or the
                         end of a word, so if you want

                             CamelCase
                             ^    ^
                             here and here

                         to be highlighted, then that won't work.

A variation of your code might be this, that highlights just the
capital letters, using `highlight-regexp's optional SUBEXP argument:
                         
 (highlight-regexp (rx word-start (group upper) (+ alnum)) 'hi-yellow 1)
