Is it possible to create a unit from a string with the Unitful.jl package at runtime without using `eval`?

Something like this:

```julia
unit_str = "mol/L"
unitful_unit = unit(unit_str)

```

I only found `u"..."` and `@u_str`, where string interpolation is not possible imho.

Edit: In the case of standalone units, it is possible to do this:

```julia
unit_str = "m"
getfield(Unitful, Symbol(unit_str))

```
