Request some assistance in resolving the following please:

Pretty sure the second error is caused by the first but unsure how to resolve the first.

I'll have to check this, but it would be worth a try to upgrade to
vibe.d 0.8.0-rc.1. It's a bit odd that this isn't caught by the CI checks.

I've gotten away from reading that book on the account that I need to improve my knowledge of programming on a whole so that I can work around the issues I'm encountering... Just finished Programming in D and am now embarking on Learning D. I will return to this after I've finished Adam's D Cookbook. By then I should be a bit more self-reliant. Thanks for looking into this and yes, I will surely be using 0.8.0 when I return to this.
