7

When storing `chrono::DateTime` values in a `date` column, the date is converted to UTC, discarding the timezone offset information. Moreover, the `FromSql` trait is only implemented for `DateTime` and not...

rand() for multisets

This package does not currently define `Random.rand(::Accumulator)` so the default implementation for an `AbstractDictionary` is used, returning a random entry `x=>count` of the underlying dictionary. For example, `rand(DataStructures.Accumulator(Dict(2=>4)))` returns `2...

Checking invertibility of matrices and solvability of linear equations

4

The functions to invert a matrix or solve a system of linear equations such as `solve`, `solve_left`, or `inv` currently throw an unspecific `ErrorException`. For example: ``` julia> M =...

Endomorphism space

Would it be possible to add an EndomorphismSpace (endowed with a ring structure) for endomorphisms on modules/vector spaces, similar to the MatrixAlgebra type for square matrices? Possibly relevant: The discussion...
