I'm still going through Joe's book, but as a C/C++ hack, I can't help 
but have some reservations about performance.  One common idiom is to 
append to the front of a list and then reverse the list when the append 
is complete.  I assume this a O(n) operation.  Is it common for reverse 
to be a bottleneck in many applications?
