Closures inside generic functions were being added to the g.target.Decls list during noding, just like other closures. We remove generic functions/methods from g.target.Decls, so they don't get compiled (they're only available for export and stenciling). Most closures inside generic functions/methods were similarly being removed from g.target.Decls, because they have a generic parameter. But we need to ensure no closures in generic function/methods are left remaining in g.target.Decls, since we don't want them transformed and compiled. So, we set a flag in (*irgen) that records when we are noding a top-level generic function/method, and don't add any closures to g.target.Decls when the flag is true.
