What is the rationale for bitfields?
I'm generally opposed to flag enums as the language support is so poor, and
unless there are very real performance considerations I'm not convinced they're
worth the code complexity cost.
I did originally try to unify Allocation and Deallocation but the usage of them
in the code base differs a bit (one is much more "try to do this" vs the
other's "do this") and I found that keeping them distinct gave clarity to the
code.
In general the way the new and delete AST construction works is kind of gnarly
in a way I wish we could avoid as I think it creates unnecessary complexity in
some places, and just causes weirdness in others, but I didn't want to combine
"lets add a new feature to new/delete" and at the same time "lets completely
restructure how new/delete work". I adopted these structs largely because there
were already two undifferentiated bool args, and adding a third made things
even more opaque, especially in conjunction with the extensive use of default
parameters.
