--- Comment #1 from Nick Treleaven <nick at geany.org> ---
> As expected, DMD does not compile this

Yes, though I've tweaked the error message in my local copy as it should be
clearer. (I'll submit it soon).

> nothing in the specification implies that this is not compilable

"If there is no AssignExpression and it is not the first EnumMember, it is
given the value of the previous EnumMember+1. If the value of the previous
EnumMember is EnumBaseType.max, it is an error."

https://dlang.org/spec/enum.html#named_enums

'the value of the previous EnumMember+1' implies that expression must compile.
