languages for these applications, and we do not expect their use to diminish. Fortunately, modern language de- sign and compiler techniques make it possible to mostly eliminate the performance trade-off and provide When your broadcast operation involves several arguments, individual argument styles get combined to de- termine a single DestStyle that controls the type of the output container. For more details, see arguments, allocate it, and then finally copy the realization of the Broadcasted object into it with a de- fault copyto!(::AbstractArray, ::Broadcasted) method. The built-in fallback broadcast and broadcast

elsize(::Type{<:A}) Return the stride between consecutive elements in the array. Optional methods De- fault defini- tion Brief description stride(A, i::Int) strides(A)[i] Return the distance in necessary. For simple functions, it is often clearer to mention the role of the arguments directly in the de- scription of the function's purpose. An argument list would only repeat information already provided StackTrace can be used in place of Vector{StackFrame}.
