It is assigning to "var+".

It's neither unambiguous nor confusing. It is assigning to "var++".
I think we should not change what is old and might be in use.
It is much easier to change what is new and can be defined at will.
If we define for example that "<name>=+<value>" appends, then we can
also define our own escape rules, for example:
var=fred assigns
var=+fred appends "fred"
var=\+fred assignes the value "+fred"
var=++fred appends "+fred"
Best regards,
