Cool. I didn't know it also works with refs. An alternative is IO::Scalar. `use IO::Scalar; ### Open a handle on a string, read it line-by-line, then close it: $SH = new IO::Scalar \$var; while (<$SH>) { # ... } close $SH;` [download] `print+qq(\L@{[ref\&@]}@{['@'x7^'!#2/"!4']});`	[reply] [d/l] [select]
