Hi, I just found a weird "bug" that makes it so you cannot compile fplus (0.2.16)

Just released the new <a href="https://github.com/Dobiasd/FunctionalPlus/releases/tag/

Hi,

and thanks for the very detailed report. 👍

I can reproduce the problem with the following minimal Dockerfile (g++ 11.2 with C++20):

FROM gcc:11.2

RUN git clone -b 'v0.2.16-p0' --single-branch --depth 1 https://github.com/Dobiasd/FunctionalPlus

RUN echo '#include <fplus/fplus.hpp>' > main.cpp
RUN echo 'int main() {}' >> main.cpp

RUN g++ -I FunctionalPlus/include -std=c++14 main.cpp
RUN g++ -I FunctionalPlus/include -std=c++17 main.cpp
RUN g++ -I FunctionalPlus/include -std=c++20 main.cpp

Output of the last line:

In file included from FunctionalPlus/include/fplus/fplus.hpp:11,
                 from main.cpp:1:
FunctionalPlus/include/fplus/container_common.hpp:154:42: error: expected unqualified-id before 'const'

      |                                          )

I'm now testing your suggested fix on a branch. The CI will automatically test it for a whole bunch of different compiler versions. 🙂
