That helps, thank you very
I want to format an array using the %(...%) syntax. How can I
change the separator? I tried to use ? and add it as additional
parameter, but that doesn't seem to work on arrays:

writeln("This works:");
writefln("%,2?d", '_', 2000); // 20_00
auto vec =

I want to import a config file at compile time, but also need a

With gcc you could do something like
-DIMPORTFROM='"MyConfigFile.txt"'. Is there any equivalent in D?
Hardcoding the config files for different versions and using that
is not an option.

Same happens with wchar.

Dchar and byte work as expected.

Assuming this function:

I was interested by asserts and how the compiler uses them to
optimize the code. So I looked at the compiler explorer to see
how and found it, it doesn't.
What I tried to do is turn a std.conv.to!ulong(byte) to a simple
cast with the help of assertions.
