Bug 500 – Struct Initializers conflict with Delegate Literals in initializers

This compiles: void delegate() y; y = { ... }; This does not: void delegate() y = { ... }; For example: void main() { // void delegate() y = { return; }; void delegate() y; y = { return; }; x(y); } void x(void delegate() y) { y(); }

Not sure it's a bug, that error is because of syntax conflict with struct initializers (http://www.digitalmars.com/d/struct.html). It's a limitation that might or might not be fixable, I dunno. (It does seem possible for the grammar to differentiate Meanwhile, a workaround: void delegate() y = ({ return; });

Otherwise, it's obvious whether a { ... } contains expressions or statements.

Fixed in DMD 0.176.
