When compilers took 20 minutes to compile one piece of code,
this makes some sense, however, now when I can be lazy and
recompile my entire design (without using make) and rerun
my simulation in the time it takes me to get coffee, why do
I worry about bloating analysis.

Instead I am worried about adding burden to the user to
do something basic like printing, and hence, am
simplifying the world from the user's perspective.

"beauty" (from Tristan) and "simplified" (from John)
mean nothing unless you explain the technical aspects.

Since I use the IEEE library in basically all of my
designs, to me it is not a thing of beauty, it is a
bit of tedious work I must do for every VHDL file.

Our intent is to simplify VHDL usage from a designer's
perspective. Does separating these functions from these
packages help a user? As we add additional types (fixed point
and floating point) if we put read/write in the base package,
then the user must reference N packages. If we put read/write
in separate packages, then the user needs 2*N packages simply
to be able to print. Is making their (and my) work twice as
tedious necessary?

Regards,
Jim
