Got it to work.
Thank you all!

:nmap <expr> <F8> ( &list ? ':echomsg 1<Bar>' : ':echomsg 2<Bar>' ) .. 'echomsg 3<Bar>echomsg 4<CR>'

works. If 'list' is set, pressing <F8> will output

1
3
4

If 'list' is not set, pressing <F8> will output

2
3
4

Note that there is no need for a colon after <Bar> and no need for <CR> before <Bar>.

Regards,
