watching a bit of code i used to compile when developing fury

void ProcessKeyDown int last_key_pressed :
int PAGE_UP{33}, int keyR{0x52}, int keyG{0x47}, int keyB{0x42}
last_key_pressed?=PAGE_UP: ToggleFullscreen .
last_key_pressed?=0x41: foo frame_size_x frame_size_y/2 3 4 .
last_key_pressed?=0x53: foo 2 3 4 5, foo 6 7 8 9 .
last_key_pressed?=0x43: MessageBoxA 0 "captionC\x00" "title\x00" 0 .
last_key_pressed?=keyR: AddBackgrounColor 0x10 .
last_key_pressed?=keyG: AddBackgrounColor 0x1000 .
last_key_pressed?=keyB: AddBackgrounColor 0x100000 .
return

i get to some thought that C switch is maybe not so much good idea
its becouse it lloks more than this key-values based container (called probably most commonly dictionary, im not sure) than a code construct... i mean maybe it it in fact better to see this as dictionary than code construct

more to say that code dictionaries could have a bigger use in C becouse you can share them semiglobally hovever im not sure if that wopuld bring doom (big mess) or something which is practically real improvement

by saring i mena it in facy can be defined

mydict (int key) = {
PAGE_UP: ToggleFullscreen ;
0x41: foo frame_size_x frame_size_y/2 3 4 ;
0x53: foo 2 3 4 5, foo 6 7 8 9 ;
0x43: MessageBoxA 0 "captionC\x00" "title\x00" 0;.
keyR: AddBackgrounColor 0x10 ;
keyG: AddBackgrounColor 0x1000 ;
keyB: AddBackgrounColor 0x100000 ;
} in fact on left side you can put not only a simple value that will be compared to key but if-like expression that uses key to check if execute contained value

some could say that it in fact makes a function
mydic(int key)
{ if(key>0) printf("a");
if(key<0) printf("b");
if(key==0) printf("c");
}

void foo()
{ for(int i=0; i<100; i++)
mydic(tab[i]);
} and maybe it is... so its like i lost the plot i thinked to generalize switch making it dictionary and returner to a concept of such if-block function but there may be something on this course of thought that is not prestented in current c syntax and semantics, im not sure it would need to be seen

(one thing is to allow such function to be inlined in (with acces to local variables)or simply contained in host function

void foo()
{ for(int i=0; i<100; i++)

mydic(int key = tab[i])
{ if(key>0) printf("a");
if(key<0) printf("b");
if(key==0) printf("c");
}

}

thet would need to be investigated (in a way i said i think, i mean trying so found something which is halfway a switch halfway a dictionary and halfway a function

possibly the form as for now could compile elements mentioned

(chars k) myswitch(chars k)
{ "aaa" : "ssccc";
"aacc" : "akjhs jshkjh"
"11" : " sddd"
if(len(k)<10) : " aaaaa"
"ruu" : { runsomething(); return " "; }
}

printf(myswitch(x))
