Why is assignment within a predicate allowed in Apex?

Hi Himanshu,

There are a few cases where this behaviour is useful in e.g. Java (reading files):

while((s = br.readLine()) != null) { … }
or C (strcpy):

while ((*s++ = *s2++) != 0);
or in Apex tests (where contact is a field of a fixture class);

insert contact = new Contact(FirstName = ‘Jane’, LastName = ‘Doe’);
