In most text-processing tasks you do not need exactly same regexp second 
time. hm, well ;) I want to have regexps without names -- yes, this 
sounds exactly like funs. But I'm against funs -- we have lists:map and 
we have list comprehension -- second one is quite easier to read in case 
of small transformations.
