v:count in mapping gets E492: Not an editor command: count

[Graham Lawrence]

:h v:count includes the following example

map _x :<C-U>echo "the count is " . v:count<CR>

which works as expected, but using

map :let @n=v:count1<cr> ...

produces E492 etc; and instead I must use

map ;; :<C-U>exe 'let @n=v:count1'<cr> ...

for it to work.

Now I have a number of mappings in alternate .vimrc files that use the 'let' form that now fails, which strongly implies that at one time that method of saving v:count did work.

So is this a recent development? Or have I unwittingly set something in .vimrc that invalidates 'let'? Or is it a vim error that is likely to be corrected by reverting to the old form? Or ...?

did you really leave out the left-hand-side of the mapping in your .vimrc or is this just a typo in your mail?

You have a very good point there, Jurgen. Somehow now, I have this uncontrollable urge to go baa-aa-aa at the moon.
