Rationale for Ada 2012
9.3.4 Defaults for generic parameters
Generic subprogram parameters and object parameters
of mode in can have defaults. But other parameters such as packages
and types cannot. This was considered irksome and untidy and efforts
were made to define a suitable notation for all possible generic parameters.
However, it was abandoned partly because an appropriate
syntax seemed hard to find and more importantly, it was not felt to be
that important. Again, it was not deemed important enough to be reconsidered
for Ada 2012.
