C++ lambda with captures as a function pointer
...id*) {return ++a;};
Converting lambda with captures to a C pointer
void (*f1)(void*) = Lambda::ptr(b);
f1(nullptr);
printf("%d\n", a); // 101
Can be used this way as well
auto f2 = Lambda::ptr(b);
f2(nullptr);
printf("%d\n", a); // 102
In case return value should be used
int (*f3)(void*) = Lamb...
