Good Morning Ken,

thanks for asking. Obviously my command of English is not good enough to 
invent self-explanatory names.

Its "EnvironmentImplementation*s*Dictionary".
Each environment implementation - yours, mine, anybody's -- should 
register an instance of a environment manager class with this 
dictionary, which in turn, dispatches most of SystemDictionary's 
retrieving and helper
methods to various environment *implementations*. In many cases the first
answer is taken.

Clearly if two environment implementations
manage an environment and a class with the same names each -- what a 
"name" is, is up the implementation -- we have a conflict,
but I presume this will happen seldomly.

Do you have any suggestion for a better
name?


HTH,

Gerald
