What is this "more interesting stuff to come"? - currently it is a bit
syntactic sugar, one might argue a feature which makes reading code
harder(*), and we are careful with adding such.
(*) Right now it is quite clear what happens if you read
$a == $b
there are a few edge cases (0 == "100000 mails ina thread") but overall
quite clear. With your patch "anything" might happen, which is hard to
detect as we don't enforce strong typing, which would give a hint.
