The Wikipedia page, mentioned in Keith's post that started this
discussion about Yoda conditions, presents two arguments
(although the second argument applies to Java code and not to C).

The Wikipedia article (as I understand it) defines a Yoda condition
as a condition in which the left operand is a constant and the
right operand is a variable; lvalueness is not mentioned - at
least not explicitly.

All agreed, if the relevant property is lvalueness instead of constness.
Although I'd expect that "lvalue" should actually be "modifiable lvalue".

Let me see if I understand your definition of Yoda condition correctly:

A Yoda condition (X==Y) is a condition that is protected against
accidental assignment, while the reverse condition (Y==X) is unprotected.
That means:
- X is an expression that is not a modifiable lvalue;
  so that (X=Y) violates 6.5.16, constraint 2.
- Y is a modifiable lvalue;
  so that (Y=X) is an accidental but valid assignment.

Examples:

  int var;
  int const con;
  char *s1, *s2;

  (42 == var);           /* Yoda condition */
  (con == var);          /* Yoda condition */
  (42 == var+1);         /* not Yoda condition */
  (42 == con);           /* not Yoda condition */
  (0 == strcmp(s1, s2)); /* not Yoda condition */

Right?
