I don't know the internals of Vim's implementation. It might be slightly faster to use "let var .= val" rather than "let var = var . val" because Vim might use extra resources to evaluate var before concatenating val in the latter, but conceptually they do the same thing and I have no reason no suspect there is a performance difference one way or the other. I just like using .= because it's less typing and makes for much shorter lines; especially when you use long variable names, or fields of a dictionary object or array items rather than regular variables. -- You received this message from the "vim_use" maillist.
