That's really interesting. Why do you prefer that to this: 
while (1) {
   $_ = <INFO>;
   return %Header unless defined $_ and !/^\037/;
   last if /^\* Menu:/;
}

This seems the same to me, only less abnormal.

> What are you doing for non 37, non menu lines? Just skipping them?
Yes, exactly so. The 37 line marks the end of the 'node'. If the function sees a 'menu' line before the 37 line, it knows that the node contains a menu, and the following code processes the menu up to the following 37 line. Lines that look different are not of interest to this function.
