The code for that function not shown is rather similar to the version that
is shown:
function
distance{T<:MutationType,A<:NucleotideAlphabet}(::Type{Proportion{T}},
seqs::Vector{BioSequence{A}})
d, l = distance(Count{T}, seqs)
D = Vector{Float64}(length(d))
@inbounds for i in 1:length(D)
D[i] = d[i] / l[i]
end
return D, l
end
Which has a @code_warntype which seems ok:

But then again the loop in this function is also not vectorised which I
struggle to see why... unless division can't be.
