Expected behavior:

using lambda1 = std::type_identity_t<[] {}>;

template<class T>
using lambda2 = []<size_t> -> T { return {}; };

After formatting:

using lambda1 = std::type_identity_t < [] {} > ;

template<class T>
using lambda2 = []<size_t>->T { return {}; };

L’issue nomina il formatter vcFormat, ma non indica alcun file sorgente né un percorso di test; inizia riproducendo gli snippet C++23 forniti con le impostazioni di formattazione elencate. Traccia la gestione da parte di vcFormat dei parametri lambda e della sintassi dei template, quindi verifica che l’output formattato preservi la spaziatura e la sintassi previste.
