I was surprised to find that there is no method on sizehint! for sparse matrices:
ERROR: MethodError: `sizehint!` has no method matching sizehint!(::Base.
SparseMatrix.SparseMatrixCSC{Int64,Int64}, ::Int64)
Is this intentional? I noticed that insert performance on sparse matrices (
setindex! in particular) is the bottleneck in my code, and I was hoping to
optimize a bit more.
