Just an update to anyone who ran into this thread (as it generated a lot of discussion and hits), a newer version of this package was [released](https://discourse.julialang.org/t/ann-flexunits-jl-0-4-mixed-unit-linear-algebra-support/135649). It’s a breaking release because I ultimately decided to subtype `Quantity` as `Number` in order to align better with existing conventions and achieve compatibility with linear algebra and DifferentialEquations.jl.

A new type called `FlexQuant` functions like the old `Quantity` in that it can contain any object as a value and does not subtype to `Number`. Users generally don’t have to worry about this, because multiplication and the `quantity` function will select the desired output type automatically. If you wish to support both types (for example, with dispatch), you can use `QuantUnion`.
