Quickly cd into a golang repo

.bashrc

# 0. Add this function to ~/.bashrc.
#    On a mac, install coreutils first and add this function to your ~/.bash_profile.
# 1. Make a shorter symlink pointing to the long golang directory name
#    ln -s ~/go/src/github.com/foo/bar ~/foobar
# 2. goto foobar
goto() {
        cd `realpath ~/$1`
}

That... is brilliant.
