Composite keys in Dictionary

[Daniel John Crowe]

Hi,

I'm just introducing myself to the slate world (0.3) and I've come up against an issue.

I've been trying to add composite keys to a dictionary.
ie:    dict at: (keya , keyb) put: val.

The dictionary uses an identity hash on the tuple, and this prevents me from using a new tuple to read the value from the dictionary.

ie:   dict at: (keya, keyb). "fails"

What is the best way around this?

Thanks, Daniel Crowe.
