Although GCC accepts the code, I don't think it does what you
think here. It will basically z will be compared with '1',
which is the value of (4 == 4), and b will become 0, or false.
OK, so it's like in the chained < comparisons.
So I presume D disallows the chained equality for the same
reasons it disallows the chained < comparisons.

I was re-reading TDPL recently, and Andrei explicitly mentions
this. The reason D disables this instead of allowing it is
because it was deemed a bad idea to allow the code to compile
with different semantics than the equivalent C code.
