I'm trying to debug stuff, so I want to add verbose logging
struct S(T) {
this() {
writeln("created S(T) with properties and ID");

I guess users can call this code from any context, but when i'd
also like to see the log output for debugging purposes. Is

Is that lib ok? Is little complicated...
converting float to string is a *very* complicated task. that lib is quite
small for what it is doing ('cause it hacks around some... interesting
cases). the *real* thing will

Hi Dlang community!
I've stumbled on an interesting issue with allocators. It seems
that we can't get disposed of arrays with const or immutable
data. Consider example below:

import std.stdio;
import std.range;

i don't think that you can make it `pure`, but you certainly can make it
`nothrow`, `@nogc` and ctfe-able. it's dangerous to go alone! take this[0].

Not one that I can see. formattedWrite doesn't seem to be pure.

It's particularly useful when dealing with stuff like C functions that
Found this out while just looking at lowerings. Wondering if
anyone knows the semantics involved here and where they are
documented?
And, is there anyway to do it with multiple variables?
I.e.
