September 14, 2012 Quick question about new semantics | ||||
---|---|---|---|---|
| ||||
I have a struct, which defines a constructor that takes an argument. Now, I'd like to new this object, to it's default T.init value (eg call new, but now constructors): -------- struct S { this(int); } void main() { auto p1 = new S; auto p2 = new S(); } -------- main.d(8): Error: constructor main.S.this (int) is not callable using argument types () main.d(8): Error: expected 1 function arguments, not 0 main.d(9): Error: constructor main.S.this (int) is not callable using argument types () main.d(9): Error: expected 1 function arguments, not 0 -------- Is this a bug? If "auto a = S();" is legal, how can "auto p = new S();" not be? |
