This I think needs to be corrected slightly.
"Programming Perl -- 3rd Ed." in section named "Bare Blocks" ( chapter 4 )
says,
... Note that this is not true of the blocks in eval {}, sub {}, or much
to everyone's surprise, do {}. These three are not loop blocks because
they are not BLOCKs by themselves; ".
so in a certain sense, these differ. I sincerely feel there is something
more to it. Also, What really bothers me is "Evaluates BLOCK in a list
context". How do you evaluate a block in scalar context? Any light on this
( or a pointer ) maybe?
