This works:

     int[][] a;
     RandomAccessFinite!(int[]) r = inputRangeObject(a);

What would be a good way to achieve something equivalent to this?:

     int[][] a;
     RandomAccessFinite!(RandomAccessFinite!int) r = 
inputRangeObject(a);

All I can say is the following compiles. I hope it works too. :) import std.range; import std.algorithm; import std.conv; void main() { int[][] a; RandomAccessFinite!(RandomAccessFinite!int) r = inputRangeObject( a.map!(e => inputRangeObject(e).to!(RandomAccessFinite!int))); } Instead of to!(RandomAccessFinite!int) one can use the cast operator as well.
