 ;;; Compilation of literals an object dumping
 
-;;; Two seperate functions are needed for escaping strings:
-;;;  One for producing JavaScript string literals (which are singly or
-;;;   doubly quoted)
-;;;  And one for producing Lisp strings (which are only doubly quoted)
-;;;
-;;; The same function would suffice for both, but for javascript string
-;;; literals it is neater to use either depending on the context, e.g:
-;;;  foo's => "foo's"
-;;;  "foo" => '"foo"'
-;;; which avoids having to escape quotes where possible
