Support for begin/end in `view(x, [begin, end])`

[haxfn]

Issue:

a = sol[[begin,end], 1]

works. But this

a = view(sol, [begin,end], 1)

does not.

The trouble here isn't the array, it's the end keyword. That's enabled with special syntax that's only enabled for square-bracket indexing: v[[1,end]]. To use views with that syntax (and support for end), you can use the @view or @views macro.
