Using a numerical value as a bin name causes error

Hi.

I was wondering if there is an issue with either the server or the client when using numeric values for bin names, or whether this is intended or not. Basically, if I try and write something to Aerospike with a bin name of 101 or even casting it to a string and doing it (string) 101 I get a -1 Generic Client Error when writing the data.

Is this intended behaviour? We would sometimes want to use an index name as the bin name, to make it easier pulling out data in a specific record. Yes, I can prefix / postfix with something but I wanted to know if this was an issue or not.

Cheers
