The following areas really need contribution and are always welcomed:
- Extending the **continuous integration** toward more exotic compilers such as Android NDK, Intel's Compiler, or the
bleeding-edge versions Clang.
- Improving the efficiency of the **JSON parser**. The current parser is implemented as a naive recursive descent parser
with hand-coded string handling. More sophisticated approaches like LALR parsers would be really appreciated. That
said, parser generators like Bison or ANTLR do not play nice with single-header files -- I really would like to keep
the parser inside the `json.hpp` header, and I am not aware of approaches similar to [`re2c`](http://re2c.org) for
parsing.

proper comparisons would be interesting.

See [issue #2324](https://github.com/nlohmann/json/issues/2324) for more information. Furthermore, assertions must be switched off to ensure reproducible builds (see [discussion 4494](https://github.com/nlohmann/json/discussions/4494)).

As Intel compilers use unsafe floating point optimization by default, the unit tests may fail. Use flag [`/fp:precise`](https://www.intel.com/content/www/us/en/docs/cpp-compiler/developer-guide-reference/2021-8/fp-model-fp.html) then.
