Extended Description

clang trunk accepts the following code.

template<>
int func( int a, auto b ) { return a + b; }

int main( ) {
    return func( 1, true );
}

It's not a specialization, and allows an empty template parameter list.

llvmbot commented 3 years ago

Sorry, meant to add, the addition of the auto parameter is when this is exhibited. 

template<>
int func( int, int ) { return 1; }

fails as it should.
