This code crashes the compiler:

int main() {
	int (*foo)(int) = 0;
}

#include <exception.hfa>

TRIVIAL_EXCEPTION( A );
TRIVIAL_EXCEPTION( B );

void defaultResumptionHandler( B & ) {
    printf("DRH B\n");
}

void defaultResumptionHandler( A & ) {
    printf("DRH A\n");
    throwResume (B){};
}

int main() {
    try {    
        throwResume (A){};
    } catchResume (B *) {
        printf("caught B\n");
    }
}

Expect

DRH A
caught B

Actual

DRH A
DRH B

Actually there is a way which is:

bool variable = functionPointer != (ReturnType (*)(ParameterType))0;

I guess a more accurate name would be "None of the initially obvious methods of converting a function pointer to a Boolean work and the one way that does is excessively complex" but that is wordy.

The "initially obvious" solutions started with simple assignment, which works in C, but when that failed I tried != with 0 and 0p and those did not work either.

I believe this is more likely to be from missing functions in the prelude.
