Matching an array-type of a C++ function signature in D, without using a D-array-type, because the compiler crashes otherwise

The problem is that the C++ compiler uses head-const for the 
array param (`float * const`), which cannot be represented in D.
What you can do is specify the mangle manually, e.g.:

pragma(mangle, "?ColorEdit4 at ImGui@@YA_NPEBDQEAMH at Z")
extern(C++) bool ColorEdit4(const(char)* label, float* col, int 
flags = 0);
