1. Resizable arrays

You might be interested in the RES-library, which also implements
resizable arrays while staying compatible to the Array-module:

Bounds checking probably makes less difference to the performance of
your algorithm than you might expect.
    

Using folding to read the cwn in vim 6+

Here is a quick trick to help you read this CWN if you are viewing it using vim (version 6 or greater).

:set foldmethod=expr
:set foldexpr=getline(v:lnum)=~'^=\\{78}$'?'<1':1
zM

If you know of a better way, please let me know.
