Bug in dealing with username of only number

[laoyang945]

say this user twitter.com/837647498
but using getUser("837647498") will get twitter.com/brezzacalda, because his/her ID is 837647498
any solutions?

Realizing that this is over a year old at this point, however it should be easy to resolve.

I didn't realize twitter names could be numeric when I first wrote this, and was trying to be clever by allowing usernames or ids to be interchangeable. I think it'd be easy to put an override or something in place. Will try to get to this soon
