Re: what difference between eval and do ?

[Eily]

Another difference:

sub hello_do
{
  do { return; };
  print "Hello from hello_do\n";
}

sub hello_eval
{
  eval { return; };
  print "Hello from hello_eval\n";
}

hello_do();
hello_eval();
__DATA__
Hello from hello_eval

return is the return value of the eval itself, but the return value of the function calling do.

As I replied before, That's because eval is a sub call, but do is a block. just image: s/eval/sub Foo/
