was wondering how fast one can do a simple "wc -l" in D.
So i made a couple short implementations and found myself confronted
with slow results compared to "/usr/bin/wc -l".
How would a implementation look like in D, which is fast?
I could not make the D program come close to wc's performance when the
data was piped from stdin. A typical run with Daniel Kozak's program:
$ time cat deleteme.txt | wc -l
5062176
real 0m0.086s
user 0m0.068s
sys 0m0.048s
$ time cat deleteme.txt | ./deneme
5062176
real 0m0.174s
user 0m0.152s
sys 0m0.072s
