On 2), if you think 1:length(A) is bad, why not forbid it from beginning (e.g. use low(A):high(A) instead)? To find an x-based array length, why not just length

On 2), if you think 1:length(A) is bad, why not forbid it from beginning (e.g. use low(A):high(A) instead)? To find an x-based array length, why not just length(A), instead of length(linearindices(A))? Decisions like such are remedies of immature early design. Also, what if I use length() on an x-based array? Abort or a wrong number silently? On 1), having two different ways to access array, the most fundamental data type, is already worrying enough. On 3), the page says "don't implement size or length". That is very uncommon in most other mainstream languages. Julia has potential to become a great general-purpose programming language, but this indexing issue will practically limit it to the numerical computing community. Perhaps achieving that is already good enough.
