if (and presumably for) can have static variables in initialization. test is due to me trying to not pollute my namespaces with static variables with imgui Raw

static_if.cpp

#include <iostream>

void run() {

    if(static bool f = false; f) {
        std::cout << "true!" << std::endl;
        f = false;
    } else {
        std::cout << "false!" << std::endl;
        f = true;
    }
}

int main() {
  run();
  run();
  run();
  run();
  run();
  return 0;
}
/*
Example usage stolen from Imgui examples:
if (static bool show_another_window = false; show_another_window)
        {
            ImGui::Begin("Another Window", &show_another_window);
            ImGui::Text("Hello from another window!");
            ImGui::End();
        }
        */
