Wow, that is pretty screwed up! I thought D was against implicit conversions that might cause problems? I'm passing an int and I should be able to append an int without having to worry about the value of the int. Instead D chose to do something very strange, awkward, and error prone.

this is legacy we got from trying to be C-compatible (along with int/uint autoconversion, and some other things). i believe that initially it was done to allow something like `char c = 32;`, and now it is too late to change it, 'cause such change will break existing code (and we're trying to not break the code without a *very* strong reason, even if keeping old code working means keeping some old quirks).
