[Issue 19057] 2.079 changelog variadic template and default arguments

https://issues.dlang.org/show_bug.cgi?id=19057 --- Comment #14 from Jonathan M Davis --- The current behavior works well with default arguments, because then they never get accidentally matched, whereas IFTI is allowed to match arguments against them, then it becomes trivial to match them

https://issues.dlang.org/show_bug.cgi?id=19057 --- Comment #8 from Steven Schveighoffer --- I think we need to find a way to change this behavior, and soon. As it stands now, it doesn't make sense, as it's only useful in the __FILE__ and __LINE__ context. It could easily be generalized to fit

https://issues.dlang.org/show_bug.cgi?id=19057 --- Comment #7 from johanenge...@weka.io --- Thanks for the support Steven. I hope this helps put the message across to be _very careful_ in making language additions / changes. This should have been a DIP. And not a PR that gets merged after a

https://issues.dlang.org/show_bug.cgi?id=19057 --- Comment #6 from Steven Schveighoffer --- OK, I misunderstood. So essentially, any function that uses variadic parameters AND a normal parameter with a default value was EXACTLY the same as a function which takes the varargs parameter and a

[Issue 19057] 2.079 changelog variadic template and default arguments

https://issues.dlang.org/show_bug.cgi?id=19057 --- Comment #4 from johanenge...@weka.io --- My concern is not about use cases. It's about breaking old code (silently), and also about strange (arguable) language behavior in the current situation. Note that before 2.079, the default argument was

https://issues.dlang.org/show_bug.cgi?id=19057 --- Comment #3 from Steven Schveighoffer --- So the use case for the new style is pretty well discussed and documented (and makes a lot of sense). The use cases for the old style are not discussed really. Looks like the only times default
