The second kind (lambda) are  essentially just function objects and their
corresponding syntax is just sugar. We need a third too, because 'class' has
still different rules wrt scoping.

The first kind is needed to do even more general things than what 'with' would
allow. From the prososal it seems that now they cannot take parameters.
