Possible unbound type parameter false positive

[densmojd]

I'm attempting to concatenate a tuple of SVector into an SMatrix, and I'm getting a unbound type parameter error I can't fix. Here's an MWE (here I just use a matrix comprehension to make things simple):

function cat_svector(v::NTuple{M, SVector{N, Float64}}) where {N, M}

    return [v[j][i] for i in 1:N, j in 1:M]

end
# special case for when no arguments are provided
cat_svector() = error("no arguments provided")

The special case was attempt to avoid unbound type parameters when no arguments are provided, but that didn't fix the problem.

I think this is a duplicate of #86.

FWIW, I still get the error if I remove cat_svector().
