Hello everyone! While researching the phobos library, I
discovered that a class can have multiple destructors if
the destructors are added via mixin injection. Accordingly,
the question is whether a description of such feature
should be added to the documentation, since the current
description is a bit confusing - ["There can be only one
destructor per
class"](https://dlang.org/spec/class.html#destructors)?
[...]
This is a bug to me, you should open an issue on bugzilla
Do you mean that it's a bug in the documentation or
implementation of the language?
Bug in the implementation of Mixin Template
Hmm, this feature is used in Phobos in
[std.signal](https://github.com/dlang/phobos/blob/master/std/signals.d#L259). Actually, this is how I found it, since I implemented the Signal functionality, but without garbage collection. It seems to me that this is an undocumented feature, rather than a bug.
Currently the spec says "If the name of a declaration in a mixin
is the same as a declaration in the surrounding scope, the
surrounding declaration overrides the mixin one", I understand
why this occurs with the current implementation, but either way
the implementation should be changed or the specs should be
clarified to explain this specific behavior with destructors.
