This is not concerning for large applications indeed. But say,
I want to implement my own `dir` (= `ls` on Unix) in D. Would
you want to use it if it took a full second every time you
wanted to quickly view a folder's contents?
To give some more context, I've been using some of the digital
mars utilities and I admire their speed. A `grep -r "goto" *.d`
could find and scan 1.7 MB of d-source files in 190ms, way before
my D hello-world was even able to enter main. As far I know,
these are just C programs. I wonder if I could make such fast
utilities in D, or whether (idiomatic) D is not the right tool
for this and I should use (better)C instead.
