Hi all, sorry for the very simple question, but I'm looking at
the "among" function in std.comparison:
https://dlang.org/phobos/std_algorithm_comparison.html#among
If I have a string array:
string[] fruit = ["apple", "pear", "strawberry"];
How do I use "among" to see if "apple" is present.

Thanks Jonathan, that makes sense. As it turns out, the Mutex

trying to use multiple cores isn't worth it.
Cheers.
Hi all, just wanting some advice on parallel processing and

Hi all, sorry if this question is silly, but is it possible to
get the address of an object within the object itself?
e.g.
class Node
{
this()
{
writeln(); // Doesn't work
}
}
auto node = new Node();
writeln(); // Does work
Thanks very much,
Cheers,
Andrew.
Perfect, thank you! :-) Works like a charm.

Hi everyone, just wanting some help with optimisation if anyone
is kind enough :-)
I have a loop that iterates potentially millions of times, and
inside that loop I have code that appends some strings together,

string key = s1 ~ "_" ~ s2;
I discovered that due to the memory

Hi guys, apologies for the silly question, but I come from the
world of dynamic languages and I'm wondering if it's possible to
set struct values basic on dynamic variables?

string firstName;
string lastName;
}
