This is not finished but I in order to use the MatrixPool, the Dense Matrix could only accept types that have static lifetimes.

[DanielLacina]

There's some situations where if you pass in borrowed values , the static lifetime condition is not satisifed.

i don't think this is the right way to go. Let's think about this for some time to have a better understanding

[DanielLacina]

Ok

or at least we need a multi-step roadmap to gradually implement this.
