What happend to the indentation? Anyway
```
$ ./inttostr -1
$ ./inttostr -2147483648
```
I like `snprintf`:
```d
import core.stdc.stdio : snprintf;
import std.exception : assumeUnique, enforce;
import std.stdio;
import std.conv;
import core.stdc.locale;
import std.format;
void main (string [] args)
{
setlocale (LC_NUMERIC, "");
auto myint = args[1].to!long;
char[27] str;
auto n = snprintf(str.ptr, str.sizeof, "%'ld", myint);
enforce (n < str.sizeof, "buffer too small");
string _dstring = str[0..n].assumeUnique;
writeln(_dstring);
}
```
```
$ ./l2s -9223372036854775808
-9.223.372.036.854.775.808
```
