Why should there be a special "reading mode" with .sty files? They are just 
read like the .tex files you create, all the commands found are executed 
(this statement includes skipping according to usual TeX rules or macros 
gobbling). The only real difference is that `@' may be part of control 
words. The \usepacke command moreover processes options (which may skip 
something) and stores them for some package management.
