While I don't disagree with Ted's suggestion,
I do want to point out that many times the
"intialization" must be done only once, preferably
during elaboration. In such cases, I call the
procedure "elaborate" and call it in the package body.
I feel the name elaborate conveys the restriction
of single initialization
In my experience, a common need for an elaborate
procedure is a variable which is an array of access
to strings. The strings may change over time and I
don't want the entire package body recompiling because
of such changes. By using an "initialize" or "elaborate"
procedure, I can make it a separate unit thus
isolating the compilation impact.
