(I only understand it about 50% so far...)
Well let me see if I can shed some light.
$ret = $1 if $g =~ /\n\s*\n((?m:^#.*\n)+)$id/;
The first bit is obviously just assigning $1 to $ret if the pattern matches. That's the easy part. Now let's look at the pattern.
/\n\s*\n # This matches your blank line between comments.
( # Capture into $1.
(?m: # Don't capture, but match this group as multiline. Wh
+ich means match '^' and '$'
# at the beginning or end of any line in the string.
^# # Match the comment delimiter at the start of a line.
.*\n # Match everything up to, and including, the newline a
+t the end of a line.
)+ # Match this group one or more times.
) # End of $1 capture.
$id # This is the key you're looking for.
/x
Very well done. sauoq++
