Then why don't you?
In the above example, spaces around the + are not only optional but 
discouraged, this would be preferred:
func(pos1, pos2, keyword=foo+bar)
but if you insist on using spaces (perhaps because it is part of a larger 
expression) just use parentheses.
func(pos1, pos2, keyword=(foo*spam*ham*eggs + bar/spam**cheese))
Strictly speaking they're not needed, but if they make it easier to read (and 
I think they do) then why would you not use them?
