Seems fine, but is this expected to pass without #665 ?

(I would add a big comment linking to Base to explain which code is copied, and which is new tests.)

[stemann]

Not sure, just trying to get the ball rolling :-) @longemen3000 suggested to add this test as a separate PR.

Thoughts, @devmotion?

[giordano]

Bump 🙂

@devmotion I've added a test that demonstrates the issue outlined in https://github.com/JuliaPhysics/Measurements.jl/pull/178/files/2a41c0cd440def23343d2565ff407eb47916d854#diff-0fafde266294d0a69e0589d46875ecceac83951c1d9a1ae32c084753539ec319R10-R22 - which is fixed by #665
