Here are some potential issues:

1. In a long project, how would I figure out which data is restricted? If the data is restricted 2,000 lines above where I tried to use it, short of an egg hunt, how would I know? (Seeing if the program dies when trying to print is an unacceptable solution.)

2. If I unrestrict the data for an operation, do I need to restrict it again? What if I forget, since I might have dozens of restricted variables? One omission could be disastrous.

3. And would people become more careless, thinking they are safe with this proposed option? (Read #2)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
