Support for setting env vars witin saws

[Bruce Edge]

This limits it's functionality as one cannot save output values to use in subsequent expressions.

saws> VPC_ID=vpc-XXXXXX

saws> echo $VPC_ID

Is there some other syntax for setting local shell variables?

[Donne Martin]

I don't think something like this is currently supported--would be a handy feature.

Thanks for the report!
