<div>
<pre>#define SELF(x) x
#define APPLY(f,x,y) x SELF(f) y
struct node {
};
node ff;
int r = APPLY(+,ff,1);
Output is:
:69:15: error: invalid operands to binary expression ('node' and 'int')
int r = APPLY(+,ff,1);
^ ~~ ~
:61:29: note: expanded from macro 'APPLY'
#define APPLY(f,x,y) x SELF(f) y
^
:60:17: note: expanded from macro 'SELF'
#define SELF(x) x
^
At least the last macro expansion should not be printed.
And whether the APPLY macro should be printed remains a question.</pre>
