Golang: int is not a type

Today I ran into a very interesting compiler error in my go program: int is not a type. Although the same lines of code that didn't compile worked a few minutes earlier.

It took me 20 minutes to figure it out. I was already halfway through a forum post on the golangbridge forums and trying to put together a minimal example when I noticed the problem. Apparently I had a typo in mit func init() and had inadvertently called it func int()!

The go compiler didn't even complain with me overriding one of it's core types.
