The following assertion fails:

assert(isRandomAccessRange!(RandomAccessInfinite!int));

Whereas this one passes:

assert(isRandomAccessRange!(RandomAccessFinite!int));

I have compiled this using dmd v2.098.0.

Can someone please tell me if this is expected behaviour and what the reasoning is behind this choice?

Thanks and thanks for the speedy fix. Being new to D, I could not tell if it was some design choice imposed by "infiniteness".

Do you know if there's a nightly version I can specify to use your fix?

Are you inheriting from RandomAccessInfinite? Then you can probably add

static if (__VERSION__ < 2099)
    enum bool empty = false;

to make it work.
