Issue ID: 17477
Summary: DMD error message for delegate with wrong attributes
is very confusing
Product: D
Version: D2
Hardware: x86_64
OS: Linux
Status: NEW
Severity: normal
Priority: P1
Component: dmd
Assignee: [email protected]
Reporter: [email protected]
When compiling this invalid program:
void f(void delegate(int) nothrow dlg) {}
void main() {
void g(int x) {}
f((x){ g(x); });
}
The error reported is:
Error: function f (void delegate(int) nothrow dlg) is not callable using
argument types (void)
This is wrong, as the argument type is not (void). It is also very difficult to
figure out what is wrong with this program from this error (when the code is
far more complicated).
A better error would be:
Error: function f expects (void delegate(int) **nothrow** dlg) but was given
(void delegate(int))
