Most nnary (or nested ternary) expressions are painful to read. This
solution seems to be a reasonable compromise.

BTW: What would be the priority of this kind of operator?

For instance, is

    Y <= A if B else C and D;

equivalent to

    Y <= A if B else (C and D);

or

    Y <= (A if B else C) and D;

?

Best regards,
