What's wrong with this picture?

#define incl(var, count) for (int var = 0; var < (count); var++)
#define decl(var, count) for (int var = (count) - 1; var >= 0; var--)

>>5,8
Are you stupid? You choose a variable name to be substituted in. If you want to use "var" for anything, it is undisturbed. And there is no "var" "object" defined. When you expand incl(i,3), you get for (int i = 0; i < (3); i++). Srsly, l2macros.
