actually, you can as well load a whole dictionary of hyphensted words 
which is quite fast too; in the process of redoing that part of the tex 
kernel we did lots of experiments, even with lua based hyphenation using 
dictionaries, just to see if it could be done; deep down all code 
related to hyphenation is rewritten; for instance there can be 
discretionaries in \hyphenation so in principle one can have more 
complex solutions
