.C++ has taken this tack: the type of 'x' is char while the type of 'xy' is
.int. It gives very nice properties when dealing with function and operator

Thank you for pointing this out. 
This means that the following program is legal in C++ and
ANSI C, and has different meanings in the two languages.
Am I correct in thinking that a design goal of Bjarne's was
to avoid the possibility of such a program? 
Is that design goal sufficiently important to motivate x3j16
to change the type of 'c' to int?

#include <stdio.h>

int main(void)
{
	printf("%d\n", sizeof('a'));
}
