module;
#include <array>
#include <string>
export module modforge.keyevent;

    inline static std::array<std::string, 256> key_map = {

Reproduction：
Use clang++ -std=c++20 keyevent.cppm The command is compiled and there is a probability of obtaining ice. The specific details are as follows:

☁  modforge clang++ -std=c++20 keyevent.cppm                             
/usr/bin/ld: /usr/bin/../lib64/gcc/x86_64-pc-linux-gnu/15.1.1/../../../../lib64/Scrt1.o: in function `_start':
(.text+0x1b): undefined reference to `main'
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
☁  modforge ls

☁  modforge ls -a
.  ..  build  CMakeLists.txt  keyevent.cppm
