The vim files for the Falcon programming language have been accepted into the official Vim repository. The next release of Vim should include the updates.
By the way, if you’re using GetLatestVimScripts, while the falcon scripts do have the line there to make them compatible I have not updated the Vim site so that’s either not going to work for you or it’s going to update to an old version. Why is this? Because I forgot my password and I have not gone through the trouble to get it reset.
