The problem with this, is that we're removing orthogonality from the
language.
Do we want to say:
$num1 == $num2 works
$string1 == $string2 works
$string1 eq $string2 works
$num1 == <non-decimal numeric literal> works
$num1 eq <non-decimal numeric literal> breaks?
I'd rather have it break in a generic way (as it does now), and teach
people what happens, than introduce a more hidden case of failure.
Or do we want to generate syntax errors for the last case above?
