This would not even compile:

$ cc -v
FreeBSD clang version 11.0.0 (git@github.com:llvm/llvm-project.git llvmorg-11.0.0-0-g176249bd673)
Target: x86_64-unknown-freebsd13.0
Thread model: posix
InstalledDir: /usr/bin

$ cat c.c

static const char[2] TEST = "F";

$ cc c.c
c.c:2:26: error: brackets are not allowed here; to declare an array, place the brackets after the identifier
static const char[2] TEST = "F";
                 ~~~     ^
                         [2]
1 error generated.
