You are right. There is a difference.
1..10 == range(1, 10 + 1)

Sure. In Ruby, you can do
i = 2
n = 5
for x in (i+1)..n do
print x
end
Can't in Ada/Pascal as far as I remember.

Well! I certainly have not done a study with code metrics. You probably
can find something online. That probably will be variable and might
depend on individual language affordances.
BTW, Ruby's times loop is another thing I find better readable for a
few cases.
4.times {
print "Something ..."
}
than
for x in range(4):
print "Something ..."
