[squeak-dev] Adding access to outer scopes to DynamicVariable

Hi Jakob,

I want to implement a dynamic lookup mechanism using dictionaries that are bound via a dynamic variable. Due to subclassing DynamicVariable using a proper name, such outer-scope access will be modular and maintainable in this scenario. I think that one would not consider this as "regular application code" but rather "meta-stuff in a framework". :-)

Hi Frank,

would it make sense to add those delimited dynamic variables to trunk?

I'm curious about the requirement for this. Is it for debugging/inspection purposes? Because I think regular application code should not try to access outer scope values of a dynamic variable. Much like it should not access any arguments of method contexts further up the call stack.

Kind regards,

Hi, there.

Please find attached the addition of outer-scope access to DynamicVariable. Any thoughts on performance and programming interface?

I would like to add it to trunk in the next week. :-)
