http://d.puremagic.com/issues/show_bug.cgi?id=11207 Summary: improve implicit conversions of function pointers/delegates Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: major Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: eberhardhoepfner gmx.de --- class A {} class B : A {} B foo(const A) { return null; } void main() { A function(const A) f1 = &foo; // compiles B function(A) f2 = &foo; // does not compile B function(immutable A) f3 = &foo; // does not compile B function(B) f4 = &foo; // does not compile } test.d(6): Error: cannot implicitly convert expression (& foo) of type B function(const(A) _param_0) to B function(A) test.d(7): Error: cannot implicitly convert expression (& foo) of type B function(const(A) _param_0) to B function(immutable(A)) test.d(8): Error: cannot implicitly convert expression (& foo) of type B function(const(A) _param_0) to B function(B) These implicit conversions should be possible. Explicit casting is too confusing and dangerous. If you make a mistake, you will end up with serious runtime errors. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
