As far as I remember that warning is only applied for return values, where moving could prevent copy-elision, but it's not the case.

I'm not sure how that applies to my comment...but I think the end result is that I will still run basic tests across compilers. Are you suggesting we needn't run tests for verification and validation?

Just saw this when I was typing the one below, I'll run the build before merging obviously, but does this not generate an elision warning?

Ah yah. I don't remember either, but that sounds right If I don't see the warning when I run the build then all is well that ends well. Thanks.

I didn't notice that throw was here. Odd choice. The compiler usually generates an implicit noexcept unless told otherwise, so I'm tempted to do a little more testing of this across compilers. I'll do this before merge.

No, I wouldn't skip them. Just meant that the change should be identical, so if it worked, it should still work _in theory_, but we are engineers, so let's see the results. :)

throw() == noexcept, however throw() is deprecated since C++11.
