# vulgar AND broken
my @lines;
$lines[@lines - s/^\+//] .= $_ while <DATA>;
print @lines
__DATA__
This

I'm sure that this is what you meant, but even this is broken as it will possibly remove the last char in the file if their is no trailing newline. 

$lines[@lines - s/^\+//] .= substr $_,0,-1 while <DATA>;

This will work: 

$lines[ @lines + 1 - s -^\053|\012--g ] .= $_  while <DATA>;
