Why don't you use :imap and :vmap separately ?
You seem to be complicating you own life by using :map
and then trying to distinguish mode() inside. Indeed, mode() does not
always work as expected. It's *not* recommended to use :map, it's
too generic. It is recommended to use :imap and :vmap.
What if you try to create two separate functions (one for insert-mode
and one for for v-mode) and use :imap and :vmap separately ?

Do you see another solution than using @- (:h registers shows that this
register is only used for text beeing less than one line)...
I want to use this to insert brackets, braces and also things like
try{
...
catch () {
}
Simple press <m-7>( to surround your text with (), ...
Or did I miss a script providing this functionality?
