the result of == is boolean, not the arguments

expected behaviour could be: 
if left-hand-type != right-hand-type
  convert right-hand-argument to left-hand type
compare left-hand-argument to possibly converted right-hand-argument

additionaly, IMHO,
as php has to deal with html forms a lot and html has no
<input type=numeric> there are a lot of places where a string 
that qualifies as is_numeric is silently treated as a numeric argument

=== , on the other hand, works like this:

if left-hand-type != right-hand-type
  result is false
  compare unconverted left-hand-argument to unconverted
