True or false. (Trying to figure out why this would be done with no
assignment).
Without an explicit assignment the variable has the value 'undef'.
In the following construct, the current value of $/ is
protected by localizing it to the scope of the block.
local() allows the value of the variable to remain the same *outside*
the block.
In this block, the current value of $/ is not changed.
Inside the block local() modifies the value of $/.
{
local $/;
# do some things here. The value of $/ is not modified in any of
the code here.
}
