I have cut some lines, and I have used a more functional style, 
that fits well for this entry. Compared to the C++ entry this D 
entry is nicer.


I greatly prefer the "verbose" option of the Python regex. And 
"g" for regexes should be the default.



This D code:

auto pairs = categories.match(r2)
 .filter!(m => languages.canFind(m[1]))()
 .map!(m => tuple(m[2].to!uint(), m[1].dup))()
 .array();

With a Python-like syntax becomes nicer:

auto pairs = [(r.to!uint, l.dup) for l,r in
  categories.match(r2)
  if l in languages];



I completely agree. The functional style is better and I miss 
list comprehensions as well. It does not require new keywords, so 
maybe it can be added to D at some point.
