My thoughts were to read .elc when avialable, I'm not sure you're familiar with the way it works for functions, but basically the docstring is replaced by a "pointer" that's a cons cell that combines the name of the file from which the function was loaded together with an integer indicating at which byte-offset the docstring can be found (the filename string is the same string used in all the docstring of that file as well as the string used in `load-history`, in terms of memory cost, it only really costs a single con-cell). So there'd be no need for "when available" heuristic. And all the code is already there to do the same for autoloads. All it takes is to start compiling the autoloads files. Stefan
