Auto-conversion doesn't work for Unitful types when using keyword arguments

[chenspc]

The Unitful.jl documentation recommends using concrete types within struct definitions. However, if using keyword arguments to create an option type object, the auto-conversion doesn't happen.

Similar usage with Base.@kwdef seems to work fine, but of course without all the nice features that come with the @option types...

julia> using Unitful, Configurations

julia> @option struct TT
           a::typeof(1.0u"m")
           b::Unitful.Length
       end

julia> t1 = TT(2.0u"m", 3.0u"nm")
TT(;
    a = 2.0 m,
    b = 3.0 nm,
)

julia> t2 = TT(2u"m", 3u"nm")
TT(;
    a = 2.0 m,
    b = 3 nm,
)

julia> t3 = TT(;a=2.0u"m", b=3.0u"nm")
TT(;
    a = 2.0 m,
    b = 3.0 nm,
)

julia> t4 = TT(;a=2u"m", b=3u"nm")

thanks for reporting, this is a bug.

[Roger-luo]

should be fixed now.

Thanks a lot for fixing this so quickly!
