Nice explanation, just one remark about
Because we are inside a do block when we use local, the value of $/ is temporarily changed, and we can rest assured that it will not affect code outside of our block (or scope).
This "(or scope)" should probably be worded more carefully. If you call another function from the block,then you are outside the scope of the block, but the value if $/ is still undef inside that function. This is one of the "features" of local that's hard to grasp, and information about it should therefore be not misleading.
$/ = 'uga';sub a { print ":$/:\n"; } a(); { local $/; a(); } a();

The rest is, as already said, well done!
