I used this feature (?) sometimes to make shortcuts for paths. But I don't think, changing the path-evaluation (only) would be enough. There are a some agressive evaluations when using a word to retrieve a value. Please have a look at with REBOL/View. You will see, that set-words for example show the same behaviour. You can also see some inconsistent evaluations in using a word! or a path! to retrieve a value. I think, if you really want to change behaviour of path-evalution you should make the the second and the third row look the same for all other values, too. And I would like them to be green for any value except of any-function! unset! and error!. And I would like to have a get-path... What do you think? CU, Frank
