For those who still use film, they can't do this. Plus, you don't always have time to chimp. Learning to do things right without relying on that little LCD is much better IMO.
If that works for you, great. There are dozens of ways to skin this cat. Bracketing is the safest because it gives you multiple versions to work with. If you bracket on a tripod, you can even use HDR to compress the dynamic range.
For me, switching to manual metering would probably be one of the last approaches I'd take, unless I was planning to take a series of shots showing the fading light.
Other approaches I might use include:
1) Spot or partial meter off of a medium to light part of the sky that I want accurately represented.
2) Shoot in evaluative/matrix or center weighted (with the sun not in the center) and trust the camera to toss out the values for the sun.
3) Zoom or recompose without the sun in the photo, partially press the shutter to lock the exposure, recompose and shoot.
4) Just fire off a set of bracketed shots with a 1.3 stop range and not worry about the metering. That's probably the approach I'd take if I was in a hurry and wanted to make sure that I got a good one.
5) If I didn't want someone accusing me of "chimping", I'd switch to manual, spot meter the different elements of my composition, determine what elements I was willing to overexpose, what elements I was willing to underexpose, and pick the optimal exposure that matched the readings that I took.
However I shot it, I'd take a quick look at the image on the LCD to see how it looks. The histogram would be less useful than normal because you are intentionally including some overexposed elements in the picture.
If for some strange reason I actually was shooting film, I'd shoot it in digital first to makes sure I had my exopsure the way I wanted it and then I'd shoot in film. Then I'd relax, enjoy the sunset, and

why I was shooting film.

If I was shooting with slides, I'd sigh and wonder how much I'd lose because of the limited dynamic range. If I was shooting print film, I'd mutter curses about the fact that all of my careful exposure work would probably come to naught when the automated printing machine decided to expose the print it's way instead of mine. I sure am glad those days are gone.
