I have uploaded a new d.vim syntax highlighting script to vim.org. Get it at http://www.vim.org/scripts/script.php?script_id=379.
Updated to D versions 1.053 and 2.039. + Merged Kirk McDonald's version 0.17 updates (http://paste.dprogramming.com/dplmb7qx?view=hidelines), including delimited strings, token strings, here strings, and some new keywords. + Merged Jesse K. Phillips' patch for some keywords and attributes (annotations). + Added some missing keywords. By the way, I haven't used D in a few years, so I haven't been very diligent in following its progress or keeping the syntax file up to date. I don't see this changing anytime in the future (as much as I wish differently). If there is anyone willing to take over maintenance, please let me know by replying to this post or in an email (my real address is inside the latest version of the script file). Jason
