The "or" should be "but".
But as "but" would be a new keyword, "except" may be better:

val = sqrt(x) except "imaginary" if x<0

Still I don't like it as the order isn't good. When there is a "normal"
case and an "exceptional" case, OK, but if the true and false cases are
more or less equally ocurring the if should be first.
