Lazy entering of names with internal $'s in package scopes
Names with internal $'s are entered in package scopes only if
- we look for a name with internal $'s.
- we want to know all the members of a package scope
This optimization seems to be fairly effective. The typical range
of package scopes that need $-names is between 0 and 20%. The optimization
seems to improve execution time of all unit tests by about 3%.
Also. drop the inheritance from Iterable to Scope. The reason
is that we now need a context parameter for toList and
other Iterable operations which makes them impossible to
fit into the Iterable framework.
