Meshes.jl test failure

Not sure what this error is from... @mikeingold any idea?

```julia
julia> using DynamicQuantities, Meshes

julia> v = Meshes.Vec(1.0u"m/s", 2.0u"m/s", 3.0u"m/s")
ERROR: StackOverflowError:
```

This worked fine like a couple of weeks ago (included in `test/test_meshes.jl`). And DynamicQuantities.jl doesn't implement any special code for Meshes.jl.

If I pass a tuple instead it gives me more info:

```julia
julia> v = Meshes.Vec((1.0u"m/s", 2.0u"m/s", 3.0u"m/s"))
ERROR: StackOverflowError:

@juliohm @eliascarv do you know why this might be? Are there any breaking changes recently that might have changed this syntax?
