Re^2: Another use bytes and length issue

If he/she is doing:

SCOPE: {
   use bytes;
   $l = length $foo;
   do_something();
}
[download]

Then the scope becomes wider :) bytes will affect anything in do_something()

Not so. `sub print_length { my ($s) = @_; print(length($s), "\n"); } my $s = "\x{100}"; print_length($s); # 1 { use bytes; print_length($s); # 1 print(length($s), "\n"); # 2 } print_length($s); # 1` [download]	[reply] [d/l]

Use a do block to limit the scope: `$s = "\x{100}";; print do{ use bytes; length $s } . ' : ' . length $s;; 2 : 1` [download] Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

well, duh. `use bytes; my $s = "\x{100}"; print length $s; { no bytes; print length $s; } print length $s; 2 1 2` [download]	[reply] [d/l]
