+--- to get the count before a mapping.  Read-only.  Example:
+--- ```vim
+--- :map _x :<C-U>echo "the count is " .. v:count<CR>
+--- ```
+--- Note: The <C-U> is required to remove the line range that you
+--- get when typing ':' after a count.
+--- When there are two counts, as in "3d2w", they are multiplied,
+--- just like what happens in the command, "d6w" for the example.
+--- Also used for evaluating the 'formatexpr' option.
+--- @field count integer

+--- Line number for the 'foldexpr' |fold-expr|, 'formatexpr',
+--- 'indentexpr' and 'statuscolumn' expressions, tab page number
+--- for 'guitablabel' and 'guitabtooltip'.  Only valid while one of
+--- these expressions is being evaluated.  Read-only when in the |sandbox|.
