use go/build to import the package and get the name

[pepin]

I was having trouble with this not resolving things, and it was because my code isn't always named according to the regex here.

With this change, godef works as expected for me.

Thanks for the change. I'm not sure this is quite right though, as it always uses the default build context, which may not be right. I need to think about the right approach here a little more.

BTW please consider naming your package paths according to the convention - it makes code hard to read when the package path doesn't match the identifier that it declares.

Agreed. This made the tool work as expected for me. Feel free to use it or discard it. Thanks for writing this in the first place.

Solved the problem for me too. Thanks @pepin !

This is one of those annoying things which makes godef sometimes not work. @rogpeppe any chance of getting a fix like this in?
