Confused about constructor

[PetrKryslUCSD]

Why does the constructor not refer to the type of the element of raw?
The lines

NIfTI.jl/src/NIfTI.jl

Line 152 in 704f7c8

NIVolume(header::NIfTI1Header, extensions::Vector{NIfTI1Extension}, raw::AbstractArray{T,N}) where {T<:Number,N} =

,

NIfTI.jl/src/NIfTI.jl

Line 153 in 704f7c8

NIVolume{typeof(one(T)*1f0+1f0),N,typeof(raw)}(header, extensions, raw)

create the volume of type Float32 instead of T. Shouldn't this be

NIVolume(header::NIfTI1Header, extensions::Vector{NIfTI1Extension}, raw::AbstractArray{T,N}) where {T<:Number,N} = let
    NIVolume{T,N,typeof(raw)}(header, extensions, raw)
    # Why is this not using T? That is the type of the `raw` array elements!?
    #NIVolume{typeof(one(T)*1f0+1f0),N,typeof(raw)}(header, extensions, raw)
end

?

Okay, now I realized there was another issue about this: #31
