Bug 18960 – Function parameter requires name with default value

As per spec this should not be possible. void main() { Foo foo = &bar; foo(); } alias Foo = void function(int=6); void bar(int v = 6) { import std.stdio; writefln("%i", v); } A simple error check can be added here: https://github.com/dlang/dmd/blob/master/src/dmd/parse.d#L2860

Hello! I have written a solution that checks if "ai" is not null at https://github.com/dlang/dmd/blob/master/src/dmd/parse.d#L3014 at if it is, it throws an error; but this creates an error message for the following program: void main() { import std.stdio; writefln("%i", 3); } The error is: /druntime/import/core/internal/traits.d(140): Error: TFunction parameter requires name with default value at == __InoutWorkaroundStruct ai == (null) /druntime/import/core/internal/traits.d(141): Error: TFunction parameter requires name with default value at == __InoutWorkaroundStruct ai == (null) From what I have gathered the at is where the type of the parameter is stored. Why is the line 140 different? (I am a newcomer so please do not judge the question) PS: I did not find a solution using the line that you have provided because there are no parameters checked in that line in the parser. Thank you in advance!

I am pretty sure I misinterpreted some parts of the spec relating to function parameter declarations. However, I cannot know for certain due to having not linked the part of the spec in question. Therefore I am closing it as invalid.
