If you could make any changes to D, what would they look like?

I know right? I'm starting to think maybe I should switch to Zig 

I have used some of these features, but then they ended up being 
annoying or unnecessary anyway:

- Module constructors make it hard to see what's happening when 
the program starts. I once submitted a D program for an 
assignment and it failed because it loaded local files for 
unittests in a module constructor, which I forgot to remove 
because I only looked at main.
- opDispatch: suddenly member introspection 
(`__traits(hasMember)`) succeeds when you don't expect it, so now 
it's accepted as a broken InputRange/OutputRange/whatever in 
generic functions.
- alias this: I use it, I encounter 
[bugs](https://issues.dlang.org/show_bug.cgi?id=19477) and weird 
consequences like unexpected endless recursion, I remove it.

It's kind of like your quote from Discord:

Nowadays whenever I can express something with plain old 
structs/functions/arrays/enums, I do that instead of anything 
fancy, and I'm liking the result.
