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.
