Interesting!

Sometimes, people want the ability to refer to the namespace already
in the block, or have the namespace "control" execution of the block.

For example, sometimes people what to get the class object while the
class is being defined. It's not there yet, of course.

In other cases (also properties) they want the name to be bound
not the one of the get method, but instead the name of the property
(of course, the make statement solves this problem already in a
different way).

Would it be possible/useful to have a pre-block hook to the callable,
which would provide the dictionary; this dictionary might not be
a proper dictionary (but only some mapping), or it might be pre-initialized.
