	# In-place arithmetic operations
	# Julia doesn't have += as a base function - it's syntax sugar for a = a + b
	# We'll create optimized in-place functions that users can call directly
	"""
	add!(A::NDSparseArray, B::NDSparseArray)
	In-place addition of sparse array `B` to sparse array `A`.
	Modifies `A` and returns it. More efficient than `A = A + B`.
	"""
	function add!(A::NDSparseArray{T, N}, B::NDSparseArray{S, N}) where {T, S, N}

Instead of introducing new functions, you could implement MutableArithmetics.jl for NDSparseArray. That would allow more interoperability, as code that makes use of MutableArithmetics would benefit from the in-place optimizations you implement without having to know about your package.
