Hello. I try using destructor in betterC code and it's work if
outer function doesn't return value (void). Code in `scope
(exit)` works as same (if func is void all is ok).
In documentation I found
https://dlang.org/spec/betterc.html#consequences 12 paragraph:
Struct deconstructors.
Why struct destructor need Druntime? Compiler must simply past
call of destructor before exit from scope or return statement.
Where is Druntime here (dynamic allocations, pointers to scopes
and other)?
I think struct destructor must work in betterC code. Otherwise
it will be one step to be likeC, not betterC.
+1 I don't see the reason.
If struct destructors were working correctly in betterC mode, it
would be possible to use RAII.
Missing RAII is a main reason of WTF messages when people see
list of betterC limitations.
