Right. Just to clarify for anyone else reading, we currently have:
    openTempFile           :: FilePath -> String -> IO (FilePath, Handle)
    openBinaryTempFile     :: FilePath -> String -> IO (FilePath, Handle)
which mask the mode, and we would add
    openFileTemplate       :: FilePath -> String -> IO (FilePath, Handle)
    openBinaryFileTemplate :: FilePath -> String -> IO (FilePath, Handle)
which do not.

Theese functions are used like this:
    openFileTemplate "/foo/bar" "bazXXX.ext"
and open a file called "baz143.ext". "bazXXX.ext" is the template.


Thanks
