clear() has been renamed as destroy() but it won't work by itself
because the OP wants a reusable object. I think, in addition to
destroy(), the default constructor should be run:

Thanks, this is a handy factoid. Reminds me of the whole __dtor
vs __xdtor debacle.

Hi,
I try to parse some hexadecimal numbers stocked in a string. So I
use this code
---
import std.conv;
string s = "B";
int value = parse!int(s, 16);
assert(value == 11);
---
But when I have several hexadecimal numbers in the string, and I
slice it, the compiler can't deduce which

You can use std.conv.to instead or assign the slice to a

This is a bit of a FAQ I think because people don't realize you
can use to and parse to do the same thing.
The big difference is parse will advance the

Is there a way to deactivate the GC, if it stands in way?
You can call core.memory.GC.disable to disable automatic collections.
.enable to turn them on again.

Hi,
I've written several small command-line utilities in D that are
to be shipped together in one package. Each one of them only
would be only a few kB in size, but they end up being ~1Mb, I
assume because every one links statically parts of the standard
library.
How can this be improved?
