ints is a set of all the integer types, using
the !ints notation is shorthand for:

fun subscript[t,u in ints]: varray[t] * u -> lvalue[t] = "$1[$2]";

Sure:

        s.[t]="hello";


Note that 'subscript' maps to .[] notation, and the result
is an lvalue so you can assign to it. Just don't assign off
the end of the array ..  it isn't safe.

They should be ..
