`eval` is also Perl's mechanism for exception-trapping.

I didn't take the title literally. The OP appears to asking why `do BLOCK` and `eval BLOCK` behave differently in the provided code. I did not set to list all the difference between `eval BLOCK` and `do BLOCK`, at least one of which hasn't been mentioned yet (`do BLOCK`'s interaction with the `while` statement modifier).

But your code already perfectly show the difference and the underlining reason between eval and do: they both return the value of the last statement in the block, eval is sub-call, so it copy the last value and return it; and do is a bit like a named block. that's it.	[reply]
