What steps will reproduce the bug?

Use node::toBaseString with enum type.

#include "src/debug_utils-inl.h"

enum SomeEnum : int {
    One, Two, Three
};


int main(){
    std::cout << node::ToBaseString<4>(One) << std::endl;
    std::cout << node::ToBaseString<4>(Two) << std::endl;
}

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

0
1

What do you see instead?

false
true

Additional information

std::forward<T>(value) has enum type which is not isomorphic with boolean type, however it is used as a boolean expression
Can be fixed with std::is_enum_v<T>
