I wonder about numerics too. Say we have a = None somewhere.
I want to increment it, so I'd say a += 8. Now if this is a parsing
app, the increment may happen everywhere -- so I'd write a function to
do it if I worry about it being initialized before. Is there any
operator/expression level support for what in ruby looks like
a ||= 0
