--- Comment #3 from bearophile_hugs at eml.cc ---
What error message do you suggest? Perhaps something like this?

test.d(3): Error: const methods (like 'S.fun') cannot modify instance members
(like 'S.v'), only constructors can initialize them
test.d(4): Error: immutable methods (like 'S.gun') cannot modify instance
members (like 'S.v'), only constructors can initialize them
