Description
begin
p :foo
else
p :bar
end
# => :foo
# => :bar
[1,2,3].each do
p :foo
else
p :bar
end
# => :foo
# => :bar
begin-else-end without rescue is useless and dangerous. (especially, do-else-end is easy to mistake)
In actually, programmer never intend to write like these.
Ruby interpreter can guard this case by syntax error.

I'm not against the removeal.
BTW, surprisingly, the following code works "as intended."
def fib(x)
if x >= 2
a = fib(x - 1)
b = fib(x - 2)
return a + b
end else x
end
p fib(10) #=> 55
