D2 code:


import std.conv;
void main() {
    to!uint("-1");
}



With DMD 2.055 it gives a strange stack trace on Windows (and on one Linux),
that I am not sure is correct:


std.conv.ConvException at ...\src\phobos\std\conv.d(1809): Can't convert value
`-1' of type string to type uint
----------------
...\src\phobos\std\conv.d(1810): uint std.conv.parse!(uint,
