I can guarantee you that keeping instructor's classroom

enforced types without automatic conversions does all this, the matches
are made once at compile-

You'll be particularly interested in RFC's 159 and 161, and discussions
on -objects. Check out these emails in particular:

While that might be useful for simple calculations, I expect it would
simply get in the way and slow things down for larger, more complex
calculations.
Alas I don't think there's any

That's not what I call a high-level language feature. People don't
want to think about that, nor about machine-level precision issues.
See REXX.
In fact, I'd rather to see a painless and transparent int->float->bignum

Some of the other RFCs on the list also appear to have been triggered the
same way.
Oh, wait...

Yes, but what about:

if ($a == $b)
Is that string comparison or numeric comparison?
