compiles in 2.011:

template decimalDigit(int n)	// [3]
{
  const char[] decimalDigit = "0123456789"[n..n+1];
} 

template itoa(long n)
{   
  static if (n < 0)
     const char[] itoa = "-" ~ itoa!(-n);  
  else static if (n < 10)
     const char[] itoa = decimalDigit!(n); 
  else
     const char[] itoa = itoa!(n/10L) ~ decimalDigit!(n%10L); 
}

char[] foo()
{
  return itoa!(264);   // returns "264"
}

the fix is to change the signature of 'char[] foo()' to const(char[]) foo()

Or even better, change all 'char[]' to 'string' with respect to D1/2
compatibility.
