@FunctionalInterface implications

[Richard Warburton]

Hi,

If the intent of an interface marked with @FunctionalInterface is to be
used as such then should it ever be extended by another interface?

I appreciate there are probably enough complex interactions that generating
a compile error if this happens would be too restrictive but what about
'morally' or as a guideline?

regards,
