Code before formatting (expected behavior):

#include <functional>

int main() {
	std::less<void> comparator;
	comparator.operator()<int, int>(5, 5);
}

Code after formatting:

#include <functional>

int main() {
	std::less<void> comparator;
	comparator.operator() < int, int > (5, 5);
}

Inizia dal percorso di formattazione di vcFormat e riproduci la chiamata C++ a operator() segnalata nell’issue, con le impostazioni e l’output prima/dopo. Traccia il modo in cui viene classificata la chiamata con template, quindi verifica che la formattazione preservi la sintassi prevista dell’operatore senza spazi intorno ai suoi argomenti template.
