> and a convoluted while where you could write a “for”

What's convoluted about it? A `for` is about as simple as syntactic sugar gets.

    for( a; b; c ) {
    }

is exactly equivalent to

    a;
    while( b ) {
      c;
    }

(OK, a variable declared in `a` will remain in scope after the while loop terminates, but the only way for this to have an effect on anything is if you intentionally refer to it afterwards, in which case you needed to predeclare it for the for loop too.)

When you're dedicated and don't have to work in a large team:

ihatetheletterf.h:

    #define cond if
    #define loop for
    #define otherwise default
    #define untrue false
    #define real float

And when you work in a (large) team, they won't likely accept weird constructions just to avoid a letter anyway.

    #include <stdio.h>

    int main() {
            int a = 1;
        
            switch(a) case 1: puts("there's always this");
    }

Switch accepts a statement. It does not have to be compound.
