One option is UnsafeArrays; see e.g. this post: [Array views becoming dominant source of memory allocation - #32 by oschulz](https://discourse.julialang.org/t/array-views-becoming-dominant-source-of-memory-allocation/6465/32). The current rule of thumb is that creating an array view will allocate if the view is used as an argument to a non-inlined function or if it is returned from a function.
