vmap inline conditional ques

Hi,

Is there a way to do an inline conditional such as for demonstration:

vnoremap <silent> <expr> <M-Left> <C-\><C-n>':let [line_start, col_start] = getpos("v")[1:2] <bar> :let [line_end, col_end] = getpos(".")[1:2] <bar> (line_end > line_start) ? "ge" : "b"<CR>'

I can do something in a function but that has several exe 'normal ...' statements and thus does not draw smoothly.

It seems I cannot get past the :let part.

thx for any help and everything vim,

stay safe everyone during this mess,

-m
