It's okay by me. The restriction on not autoconverting hex and octal stems from the days when 0777 was assumed to be octal. Since we've changed that to 0o777, it's much less likely to autoconvert zip codes to a different number. We can allow 0b111 as well. (Scientific notation is already allowed in Perl 5 autoconversion.) : What about "Inf" and "NaN" in numeric context? We should be intelligent about Inf and NaN, which means Inf is infinity but Info is 0 (plus warning). NaN is not a number, while NaNa is 0 (plus warning). We also recognize +Inf and -Inf. Larry
