does this mean that i can include whatever local variables (local to
the block) that i  need between the || right after the block
parameters. would such variables  not affect any variable of the same
name used outside the block and not have any effect on such variables?

for example,

g = 5; puts g; [1, 2, 3].each do |f, g| puts f, g; end; puts g

now gives me:

5
1
nil
2
nil
3
nil
nil

Under Ruby2, would it give me the following?

5
1
nil
2
nil
3
nil
5
