(passing an IN parameter or read-only variable as a VAR receiver is no longer allowed).
This is not a surprise because this change is the most significant incompatible change of 1.7
and it was of course possible to do the required adaptations.

However, this change may also hit other users and complicate the upgrade to 1.7.
I therefore took a closer look and found out that almost all of the problems
could have been avoided by small refinements in the core system.
Those changes would also avoid changes in some other BB modules
that have been done for #38 and could be undone.

The changes are simply to use IN for the receiver parameter of
methods that don't change the receiver. This approach has
already been applied to module Meta as part of #38.
It would only be needed to also apply it to TextMappers.Formatter
and the various Dialog types such as List or Tree.
