Error: found `{` when expecting `;` following statement

Adding the semi-colon, `*c == d;` would likely cause:
Error: `*c == d` has no effect

Also multiplying (a+b) by a pointer is illegal, and c is probably 
a pointer if it can be dereferenced. In theory a UDT could define 
opUnary!"*" and opBinary!"*", is that likely?
