Previous dev created a switch statement on a boolean flag. WTF

When 0 is particularly large, it's nearly as large as a little bit of 1.

Shiiiiiit

I do that as well sometimes. Instead of a bunch of if-else one could write:

@highlight
switch (true) {

case thing1(): { ... }
case thing2(): { ... }
case thing3(): { ... }
default: { ... }

}

@olback wth that's actually pretty nifty when I think about it. No way I'd accept it in a PR though.

@olback if-else is more efficient in this case. Also, most languages only support compile-time constants as case values.

Nullable boolean?

switch(Val){
case true:
Damn() ;
default:
ImAnIdiot();
}

@s0LA By optimising it on hardware level. That's nearly as good as optimising the idle task of an operating system. :-)

COBOL has support for reverse switch-case. This can sometimes be useful if one three different variables can have one specific value.

@highlight
EVALUATE "Y"
WHEN VARIABLE-1 ...
WHEN VARIABLE-2 ...
WHEN VARIABLE-3 ...
WHEN OTHER ...
END-EVALUATE

It's OK, he just wrote future-proof content for when you port your software to a system that supports qubits.
