Coq.Library_fileSourcetoc libs Returns the list of constants and inductives found on .vo libraries libs, as pairs of name, typ. Note that the constants are returned in the order they appear on the file.
NOTE that (unfortunately) this is a very expensive process, similary to Coq's Search, as this routine will have to traverse all the library objects in scope.
Hence, we provide a slightly more efficient version that can do multiple libraries but with the same complexity.
There have been several upstream Coq PRs trying to improve this situation, but so far they didn't make enough progress.
