I see you have a solution, but with the 'nocompatible' settings (and
'cpoptions' at its "Vim default") I would have tried
:map ,blah :%s/<Bslash>(foo<Bslash><Bar>bar<Bslash>)//g<CR>
i.e., replace
\ by <Bslash> everywhere in the {rhs}
| by <Bar> everywhere in the {rhs}
and add <CR> at the end, to execute the ex-command.
See ":help keycodes"
I might also have used a shorter {lhs}, for instance <F2> or <S-F8>
A different possibility would have been not to use a mapping at all, and
to recall the :substitute from history. Depending on circumstances, one
or the other may be better.
Best regards,
Tony.
