I'd call it @constfold.
That's a good name. Descriptive and short.
I'm not going to try to push this suggestion any harder, since it
got no support on the first time I tried it. But I'd like to
mention just one thing that came to mind:
The generic solution without any extra function attributes:
template ct(alias expr)
{
enum ct = expr;
}
Literal of type TypeWithNonTrivialConstructor:
ct!(TypeWithNonTrivialConstructor(2.5, 7.5))
The above solution throws the responsibility of the correct use
of TypeWithNonTrivialConstructor on the end-user. Whereas a
@constfold attribute on the constructor of
TypeWithNonTrivialConstructor automates the correct behaviour.
