(read-expr "08") reads octal?

[Thorstein]

This behavior was a little unexpected.

It says in the manual that those expressions are octal.

Aha!:

"Octals start with an optional + (plus) or - (minus) sign and a 0 (zero), followed by any combination of the octal digits: 01234567. Any other character ends the octal number. Only up to 21 octal digits are valid and any more digits are ignored."



Thanks.
