I would like the compiler to determine the union member by its type
when possible.

struct SExample
{
    int i;
    float f;
};

SExample myArray[] = {
    { 10 },    // Initialized to i member as int
    { 3.14f }  // Initialized to f member as float
};

No designators, but rather by initializer type the appropriate member
is populated into. And if it is ambiguous, such as using 5 for a union
containing both int and char members, then it must be explicitly cast,
or a designator must be used.

Best regards,
Rick C. Hodgin
