The docs when using ?StaticArrays.qr in the Repl writes that: The following functions are available for the QR objects: inv, size, and \.
However, this seems to not be true for the array types in StaticArrays.

using StaticArrays

A = randn(4, 3)
b = randn(4)
StaticArrays.qr(A)\b # works fine

A_static = SMatrix{4, 3}(A)
b_static = SVector{4}(b)
StaticArrays.qr(A_static)\b_static # not working

It would be great to have this functionality implemented.

Yes, very surprised to find this doesn't work. Also ldiv! would be great.
