This works.

This doesn't.

It's probably an artifact of getting rid of octal literals and is clearly a 
bug - though you probably shouldn't be starting literals with 0 due to 
possible confusion with octal literals anyway (00 - 07 are permitted because 
they're the same in both octal and decimal, but any other number literal 
starting with 0 is illegal).

The error you get for something like

auto n = 08;

is a bit off too

q.d(5): Error: semicolon expected following auto declaration, not '8'
