Methods
- __contains__(self, key)
- __delitem__(self, key)
Delete an item from the ExpressionContext -- either in the underlying context, or if an already cached expression, delete it.
- __getitem__(self, key)
- __init__(self, underlying_context, **traits)
- __setitem__(self, key, value)
We don't allow setting an expression per se, so it passes through to the underlying context. Hopefully this won't be a problem in the future due to plots or other listeners trying to change values. Theoretically one could store the inverse of a function and allow this if the function was invertable
