I just posted a small common lisp library to my github account named Symbol-Munger. Symbol-Munger provides functionality to ease conversion between the same symbol in different environments.
For example, when generating common lisp classes from a database schema, I want to change column names into lisp slot / accessor names, and then later when I am displaying that common lisp slot on the screen I want to display its slot-name as an english column header. (IE: my_db_col > my-db-col > My Db Col)
I have had this code laying about for years and use it everywhere frequently. Earlier today while cleaning other code, I ran across this TODO in vana-inflector, and realized I already had code that performed this function. This library contains one function that does the bulk of the work (normalize-capitalization-and-spacing) and many functions that set default arguments to that one (lisp->english, english->camel-case, english->keyword. etc). Its only dependency is iterate.
