I'm trying the static bindings for glfw of bindbc on Windows,
using the pre-compiled .lib files from the lib-vc2015 folder in
the official download.

With LDC using the Microsoft MSCV linker, everything works. I can
either add this:

As I see it, a ubyte 0x20 could be decoded to an ASCII char '

sense to decode a char to a wchar or dchar. Anyway, you've
shown me how decodeFront can be used, so great!

This is the overload you want, let's check if it matches:
ref S str - your InputRange can be

I am debugging a case where operator overloading seems to break
when I define the opBinary templates in a mixin template. On my
own simple test-case it worked fine, so I'm trying to reduce my
current code with dustmite.
The file tree is simply:

make front and popFront separate functions, instead of having
popFront return the front. I suppose it is useful sometimes to be

I don't know if your situation allows it, but you can mark f
explicitly as always @nogc. If your design assumes that it's
@nogc, it's a good idea to add the attribute anyway.
You can also use the C printf
