Ah, sorry, I thought you wanted us to extend "expr".

Hmm... Yes, but it could also be read that only decimal

It also says, for example:
expr1 + expr2 Addition of decimal integer-valued arguments.
So, under your interpretation, "expr 010" would print 8, but "expr 0

The current documentation says under "expr invocation"
Operands are either integers or strings. Integers consist of one or
more decimal digits, with an option
I recently suggested that expr could be used to convert values from
user input or other places to strict decimal form. And it can
validate non-numberic input easily. Example:
expr 08 + 0
8
expr foo + 0
expr: non-numeric argument
However, I can't see anywhere that expr is defined to alwa
