This handles the two dependencies
SparseArrays.jl
andStatistics.jl
as weak dependencies. Indeed, the only reason LinearMaps.jl depended on these was to overload their functions. Otherwise, LinearMaps.jl has always been independent from these two. Moreover, users could not call, say,sparse
without loadingSparseArrays.jl
, so this is a clear case. This brings package load time of pureLinearMaps.jl
down to below 20 ms (from about 300 ms, if not 500 ms and more) on current Julia nightly with SparseArrays.jl out of the sysimage).Resolves #207.
