A can be strings or char, how can I easily deal with both? (e.g.,
a.length = 1 for a being a char... and also a[0] = a, so to speak).
That is, I
void foo(A...)(A a)
{
foreach(aa; a)
{
for(int i = 0; i < a.length; i++)

That is, I want chars to be treated as strings

I'm trying to use a binary heap initialized with one element.
However, this always seems to cause a range violation for some
reason. This small example will do it:
import std.stdio, std.container;
void main() {
auto pq = heapify([5]);
pq.insert(8);
}
...And it produces this error: https:/
Might I suggest that you simply define an enum for UnixEpoch
that's a
SysTime. Then you can do whatever you want.
ping on this.

Hello folks,
The default dmd.conf settings for 64-bit environments include the
-fPIC flag (for good reason), but the settings for 32-bit
environments do not. Any particular reason for this?
Thanks & best wishes,

Main reason for D not supporting the name-to-pointer mapping? I don't
think so because as far as I know this has been the case since very
early on but UFCS came very much later.
More likely due to properties, i.e. calling functions without
parentheses.

You wouldn't as the std lib doesn't work with it yet.
