The fast-tags package
Yet another tags program. Like hasktags, it uses its own parser rather than haskell-src or haskell-src-exts, so it's fast. It understands hsc files, though not literate haskell.
In addition, it will load an existing tags file and merge generated tags.
The intent is to bind it to vim's BufWrite autocommand to automatically keep the tags file up to date. This only works for files changed by the editor of course, so you may want to bind 'rm tags' to a pull posthook.
No emacs tags, but they would be easy to add.
Not using a real haskell parser means there are more likely to be dark corners that don't parse right.
Only top-level functions with type declarations are tagged. Top-level functions without type declarations are skipped, as are ones inside let or where.
Code has to be indented "properly", so brace and semicolon style with strange dedents will probably confuse it.
