Your unit tests are not good enough, they miss some important corner cases.

I agree that's much simpler, but s1 ~ s1 doesn't perform too well I
think. Always creates a new heap allocation and copies the array..
The version written by Pelle is better. On the other hand performance is not an
absolute thing, it's good enough or not good enough, and in many

Nice clean solution. I suggest to add pure and two const in the signature.
canFind isn't really the best possible name, is it?

Some name/APIs of Phobos are not the best possible, they were often
invented by a single person. I don't know if contains() or isIn() are
better.

I was reading about the various range templates in std.range and I found this:

Seems simple enough. But I dont understand it's implementation, this from

Ah, you're right. Whenever I see the square brackets my brain automatically
things we're indexing something. I'll blame that on C. :p
Thanks.

So what's the word on this? Will we have simple indexing of tuples via T[] or
do we still need T.field[] and T._1 ? The situations is the same in 2.048 as it
was in 2.047.
There are more examples of tuples being used via T[] in some Phobos code
examples (which don't compile and I've reported
This is from TDPL page 407:

// Read loop
foreach (immutable(ubyte)[] buffer; stdin.byChunk(bufferSize))

send(tid, buffer);

Hello,
I decided to exercise my skills in D a bit and wrote an implementation
for an echo server using D. I figure before I post it to the site, I'd
post it here for comments as I'd like to get the best possible version
on the site vs. something that's half-assed. Considering I'm very new
With dmd 2.048 this code:
import std.stdio: File;
void main() {
auto f = File(TEST.ppm, w);
f.writef(%c, 50);
}
Prints at run-time:
std.format.FormatError: std.format integral
So to write a char I've had to use:
f.write(cast(char)50);
Partially unrelated: is is possible to perform
15 matches
