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}. (Examples with [...] indicate that output may vary de- pending on how the code is run.) julia> example() = stacktrace() example (generic function with
