i see...

so after

if false
  foo = 10
end

now, bar = foo || 0  will run.

Since for instance methods, the setter method can be foo=()

so how about just a method not inside a class, can it be named "foo=" as 
well?  if so, how does Ruby know  foo=1 is really an assignment or a 
method call foo=(1)?

Ruby doesn't seem to like "foo=" as a method:

def foo=(i)
  p "ha", i+1
end

def bar?(i)
  i % 10
end

p foo=(1)

p foo

p bar?(22)


it will print out
