Re: question about eval(bare word etc);

You are doing the equivalent of

print Dumper [[gid, 0509b1300000000000BAB002]];

Perl can make sense of the bare word gid (treating it as a string), but the 0509b1300000000000BAB002 gets it confused. It starts with what looks like a number, 0509, but b1300000000000BAB002 is not something that can follow a number in this context.

Perhaps you meant

$a = q([['gid', '0509b1300000000000BAB002']]);

Thanks! script works when put the string into a pair of single quote. But I found this may not be the true cause to make the problem. actually, user put that string in double quote, and eval remove it in silence. Anyway, I realize eval input from users is very danger, it treat them with some extra actions background, and even it would be made use of by some ppl, though it looks a easy way to implement. I've changed the design and thus the question is going away .	[reply]
