Thanks everyone for the replies! I just thought it was weird that
implicit construction is seemingly supported when directly
initialising a struct but not in any other case. I guess it's
because it's clearly less ambiguous.

For the program you've written, I'm happy it doesn't compile,

explicitly. In this case you can change your definition of None
to use alias this and it will compile:
The alias this doesn't work generically, though. Either way I
agree that implicit construction, if it was present in D, should
not be the default, instead being opt-in like say through an
`implicit this(...)` or whatever instead of C++'s horrendous
implicit by default behaviour.
