I started working in a pet shop when I was 12. This girl bought a baby Burm and was a regular customer. By the time I was 17, her snake was 14 ft long.
She bought several habitat upgrades along the way, the last being a 150g tank before having to build a custom enclosure.
The snake was handled regularly throughout it's life; never bit and the girl had a good feel for it's personality. Burm's, afterall, are pretty gentle snakes and have a great reputation.
She stopped coming in on a regular basis and I left to find a real job.
A few years later, I stopped back in to my old pet shop and asked my former boss whatever happened to the girl with the 14 ft burm.
It seems she was cleaning out the enclosure and had put the snake on her bad. She's done this a hundred times before; the snake would just lay there, coiled up on her bed. She's just about done cleaning up when without warning, she takes a bite to the face-from about 8 feet away!

Fortunately, he didn't clamp down-he just hit her with an open mouth so she only needed moderate reconstructive surgery on her face.
The entire family loved this snake and cried when they donated it to the Bronx zoo. Nobody knows what happened to the snake but the girl just couldn't keep it anymore, despite her emotional attachment.
This is a true story, and there are a few points to take from it.
Snakes are wild animals. It is wise to never forget that, especially when dealing with a 14 footer.
Had this girls Burm decided to wrap a few coils around her, she would be dead. She's lucky the bite was a fear/aggressive behavior and not a food driven strike or she would have died in her own bedroom (Her parents were downstars and surely would not have noticed).
Also, had this snake been a hard biter, like a Retic for example, she would have been hurt much more.
To the original poster, I say go ahead and get an Eyelash viper. It will probably die before it has a chance to kill you but your friends will think you are very cool.
