Need help with union trick: summary of replies

[Rahul Dhesi]

I sort of like calling the union substructure by tiny names like x, y,
z etc.  Then references become struct_name.x.field_name, and the ".x."
is almost not noticeable.  The idea is to use a small meaningless name
(sort of using i, j, k as loop counters) so the meaningfullness (to
coin a noun) lies entirely in the name of the structure and the name of
the field.
