import std.algorithm.comparison;

void main()
{
   clamp(short.init, short.init, cast(const)short.init);
}

2.067.1 to 2.098.1: Success and no output
Since      2.099.1: Failure with output:
-----
onlineapp.d(5): Error: none of the overloads of template
`std.algorithm.comparison.clamp` are callable using argument types `!()(short,
short, const(short))`
/path/to/dmd.linux/dmd2/linux/bin64/../../src/phobos/std/algorithm/comparison.d(579):
       Candidate is: `clamp(T1, T2, T3)(T1 val, T2 lower, T3 upper)`
  with `T1 = short,
       T2 = short,
       T3 = const(short)`
  must satisfy the following constraint:
`       is(typeof(val.lessThan(lower) ? lower : val.greaterThan(upper) ? upper
: val) : T1)`
