Why not extend array operations to full Fortran90 power ?

I realized a problem with (2), it's actually not possible to rewrite it 
using existing constructs because foreach doesn't support multiple 
iterators. You can use std.range.zip:

foreach(i; zip(Y, X)) i[0] = sin(i[1]);

But it's not a core language feature. Before we could extend array 
operations to support the example above, I think D would need native 
support for multiple iterators.
