https://issues.dlang.org/show_bug.cgi?id=5803 --- Comment #6 from Rainer Schuetze --- I haven't looked through the full diff, but the very first two lines are still valid: both the module declaration and the other declarations are optional which isn't covered by the grammar found in the language spec. --

They have very different semantics. Given only a StructLiteral, you can always work out what type it is. But with a static initializer, you know nothing. This might be the only thing in the language like that. It's not implicit conversion, they don't have an initial type to convert from. So auto x = StructLiteral(); works, but auto x = structStaticInitializer cannot. Consequently, you can use a struct literal almost anywhere you can use a struct variable. I've tried to get them deprecated but I don't know if that will happen. They are one of the most complicated things in the language, and the implementation is *full* of bugs. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

Maybe I oversimplified here, but I was hoping for a generalization of the array/struct initializer and literals. IIRC the StructStaticInitializer is said to be deprecated anyway, but it might actually be possible to interpret it as a literal inside expressions with implicite conversions, similar how dmd deals with arrays, because the parser cannot decide which type of array a variable is declared as until the semantic pass. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

One fairly big mistake in there: there seems to be confusion between
StructLiteral and StructStaticInitializer.
Foo z = { x: 7, y: 56};
is a struct static initializer, not a struct literal.
Foo(7, 56); is a struct literal.
