According to the "Integer Literals" section here:

   http://dlang.org/lex.html

Decimal literals are resolved as either int or long. 
9_223_372_036_854_775_808 cannot fit either of those types.  If you want 
ulong, you must either write the literal in hexadecimal or binary format 
or provide the UL suffix.
