indexing a slice with an array causes an error inside ndslice

[John-Colvin]

e.g. mySlice[[1,2,3]] gives

/Users/john/.dub/packages/mir-0.10.2/source/mir/ndslice/slice.d(1556): Error: no property 'i' for type 'int[]'
/Users/john/.dub/packages/mir-0.10.2/source/mir/ndslice/slice.d(1557): Error: no property 'j' for type 'int[]'
/Users/john/.dub/packages/mir-0.10.2/source/mir/ndslice/slice.d(1557): Error: no property 'i' for type 'int[]'
test.d(8): Error: template instance mir.ndslice.slice.Slice!(3LU, ulong*).Slice.opIndex!(int[]) error instantiating

it should either work or should error at the API level, not internally.

This code should compiles with v0.11.1.
