For what it's worth, this is also the case for most operators in Ruby, it's 
just that pretty much all Ruby operators have special syntax. This makes 
sense, I think -- for example,

a.foo = b

is equivalent to

a.foo=(b)

which seems a lot more manageable to me than

a.foo.=(b)

What would a.foo be returning, then? You could do it, it would just be clumsy, 
and wouldn't work nearly as well with immutable types -- and all the basic 
Ruby numeric types are immutable.
