Hi! A new version of this package *(v0.1.0)* is under the name *PairwiseListMatrices*:
https://github.com/diegozea/PairwiseListMatrices.jl This package works on Julia 0.4 and allows you to use a pairwise or paired list as a matrix (using aprox.* N*N/2* instead of *N*N *space). There is an example in the README with some benchmarks at the end (this list are faster in some situations and slower than a full matrix when reduction along dimensions are required). Best,
