I have been very busy these last  days that essentially I haven't read =
any
emails on this thread since my answer. I saw that type casts were =
mentioned
in the mean time. What casts?!

These "type conversions" are not to be used regularily, but only in =
specific
cases when doing otherwise introduces significant disadvantages. Use
encapsulation and abstraction for the usual stuff (access via member
functions and stuff).

You will find that in most cases that the implicit type conversions you =
need
will occur via the implicit calls of constructors and the creation of
temporaries (which sometimes we wish to avoid thus the use of the =
keyword
explicit, but that's another story).
