    Please avoid

always (unless you have reeeally good reasons)


std::bind
std::function
std::type_info
std::vector<bool>
va_*
std::valarray
std::list
assert (instead use a thrower version / contracts)
all locales stuff
.at() methods as it's more likely to be a problem with your code
`#include <headerFromC.h>
void*
setjmp and longjmp

in most cases


std::*map, extract and merge makes it so that each node needs to be allocated individually...
and usually most standard containers other than std::vector/std::string
<c[some header]>
std::shared_ptr, this one is on the edge to being in the "always" section
all rtti
std::regex (maybe)
virtual, prefer concepts
sfinae, prefer concepts
EXIT_SUCCESS and EXIT_FAILURE (just why?)
using [unsigned] char to represent bytes; prefer std::byte
std::endian (to contest against it, because it sucks and steals a namespace)
std::to_chars (it's a weird api)
std::vformat and std::vformat_to...
... and the whole formatting stuff if possible
potentially avoid futures as better alternatives now exists
std::span, prefer using concepts
