Again, this splits the language into two halves.  A library language
and a scripting language.  Extremely confusing and sets a very, very,
very dangerous precedent.

And consider the maintenance nightmare.  I have a routine in a script
which I decide goes better in a library.  Suddenly, I'm playing under
a different set of rules.

Its not worth it.  Its not worth saving 10 characters.  Take a typing
class.

The amount of typing doesn't matter.  Its the fact that you're putting
it on the command line when you run the program that's the problem.
The way strict is used, its either on or off.  There are very, very
few cases where you want sometimes to run a particular program with
strict and sometimes without.
