Description Walter Bright 2023-01-08 06:28:13 UTC 
From Max Samukha:

Simple test cases still don't compile:

string foo()()
{
    string a, b;
    return a ~ b;
}

enum s = foo();

./dmd -c -betterC test.d
test.d(4): Error: array concatenation of expression `a ~ b` requires the GC which is not available with -betterC
