internal error on admittedly bad statement

[stevesmoot]

6.1.0-rc1

module testme;

import zeek;

public type junk = unit {
   fire : /foo .*/;
   on fire {
     local k:string = zeek::is_orig ? "a" : "b";
   }
};

It should be is_orig(), generates:

$ spicyz -o test.hlto test.spicy
internal error: unexpected type, want hilti::Declaration but have hilti::node::None

The actual issue is a Spicy issue when one uses a function name in a place where an expression was expected and reproduces with the following pure Spicy code:

module foo;

function fun(): bool { return True; }

fun ? 1 : 0;
