Thanks for your comments. I was thinking the same thing, i.e. 
that maybe future implementations of the  compiler can optimize 
the overhead away. If CP is THE major thing in D (and it makes 
perfect sense that it is), then the compiler (and syntax) will 
adapt to it over time, I guess (and hope).

I'll try to introduce CP/Ranges where ever it makes sense from 
now on. It was unbelievable how well the code worked once I could 
free myself from the loop. And I can take the components and use 
them "as is" in a separate program I use to add entries to the 
lexicon source files. I'm only wondering how to integrate the new 
pattern properly into an otherwise OO framwork. I seriously 
wonder whether CP/Ranges will make OO obsolete. After all, 
structs are "classy".
