[Chicken-users] environments egg

[Daishi Kato]

Hi,

Is it possible to add

(environment-layer ENV [EXTENDABLE [SYMBOLS]])

that creates a new environment over a base environment ENV,
and the binding is firstly lookuped in the new environment,
and then (if it's not found and not deleted) lookuped in the base environment.

Better naming would be nice instead of environment-layer.

Thanks,
Daishi
