Some of the changes since the last release caused a regression in CTFE:
---
import std.conv;
enum short a = 1000;
enum b = to!string(a);
---
now fails with:
---
CTFE internal error: unsupported assignment cast(uint)cast(int)n /= base
Assertion failed: (e1->op == TOKarraylength || e1->op == TOKvar ||
e1->op == TOKdotvar || e1->op == TOKindex || e1->op == TOKslice),
function interpretAssignCommon, file interpret.c, line 3343.
---

As it probably clear to you what's happening here anyway, Don, I didn't reduce it any further so far. This is the corresponding source line: https://github.com/D-Programming-Language/phobos/blob/master/std/format.d#L1105

Reduced test case. This has never worked in CTFE, so it's a change to Phobos that exposed it. The fix is simple.

int regress()
{
    ubyte n = 6;
    n /= 2u;
    return n;
}
static assert(regress()==3);

Oh, you are right, sorry ? I forgot that value formatting was unified since DMD 2.056. In any case, thanks a lot for the quick fix!
