It makes the language simpler conceptually: all variable declarations
are of the form
<type> <var> <optional initialiser> [, <var> <optional initialiser>]* ;
Even a compiler that is only 1/3 decent% will warn about unreachable
initialisers.
Note that the <optional initialiser>s are, as Doug has already pointed
out (it seems to require a great deal of repetition to get these to sink
in), treated as though they were executable statements when they apply
to automatic (as opposed to static or global) variables.
